Cant play online on Wii U because of p2p problem.

[hexed skiff]

Does someone know how to unblock p2p connections on my router so i can play online with the Wii U? Yes my Wii U is modded, i use the latest version of Aroma and everything else is working fine except PLAYING🫤.

[limber scaffold]

Error code?

[hexed skiff]

118-0156

[storm grail]

I've heard that you should check your router's DMZ settings.

[hexed skiff]

How do i do that?

[storm grail]

I do not know about your router. On my router, find DMZ settings and enter IP adress of wiiU allows p2p.

[slim lantern]

You might have a bad NAT type

[dusty jolt]

Wish the Wii u told you what NAT type you have

[pale hawk]

It does

The 3DS does it too.

[dusty jolt]

Does it actually, I’ve never seen anything that tells you info about NAT type

[pale hawk]

The Support Code reveals the NAT type

220 is strict,
120/122 is normal/moderate (122 DS-lite)
110 open.

[dusty jolt]

Ok I never knew that

More you know

[pale hawk]

In "Switch" NAT type language,

220: C, D, E, F
120/122: B
110: A

[slim lantern]

did.. not know that

[dusty jolt]

Nether did I

[pale hawk]

Had to update. 110 was A, not 100.

[slim lantern]

@pale hawk by the way how do you know this

This appears to reflect my settings so it must be correct

[pale hawk]

Know what? The Support Code?

[slim lantern]

Know that the support codes reflect NAT types

[pale hawk]

I realized some time ago the 3DS/Wii U always showed 220 when the Switch said D. So I started making test environments inside my home network (I can give me every NAT type) and so was 220 always strict (D), 120 normal/moderate (B) and 110 open (A).

[dusty jolt]

Huh

fancy that

do we know what the 2nd pair of numbers mean?

[slim lantern]

You figured this out yourself?

[pale hawk]

I personally don't know it. However I'm getting 00 in WiFi and 01 on Ethernet/LAN.

So probably interface specific.

[slim lantern]

That’s probably what it’s for then

[pale hawk]

Yeah (I guess lol)

[dusty jolt]

Ok that makes sense

guess on the topic of NAT types, wonder what port pretendo uses

[slim lantern]

Wow ok I shall use this information because this is extremely handy

[pale hawk]

Sure, feel free.

[hexed skiff]

Im really happy u guys found out so much, but for me technic noob could someone explain in short terms what i could try exactly to fix this Problem?😆

[pale hawk]

Are you german?

I see the "Leck mich" lol

Either way, do a connection test and tell the support code.

[hexed skiff]

Yes i am du you speak german i think it could help

Do*

[pale hawk]

Ja, ich spreche deutsch.

[hexed skiff]

Super

Also ich soll jz einen verbindungstest machen ?

[dusty jolt]

time to bust out the translate plug in so i can still watch from the side lines

[hexed skiff]

AHAHAHA

[pale hawk]

Ja. Weil da ist ein Support Code. Und der kann anzeigen, was nicht stimmt.

[hexed skiff]

Okay okay warte

Lets continue in english so FourHawk can follow

Support-Code 220-01 bottom Right

[pale hawk]

Yeah, Strict NAT

[dusty jolt]

Na na don't worry about it, speak german if it's easier

[hexed skiff]

So what does that mean

[pale hawk]

A strict NAT interferes with the matchmaking protocol.

Do you use mobile hotspots?

[dusty jolt]

and could just flat out cause connections not to be made

[pale hawk]

Or these mobile routers like o2 Homespot/VF GigaCube?

[hexed skiff]

Exactly

[pale hawk]

o2 or VF?

[hexed skiff]

Vodafone Homebox or something

Vodafone

Its a temporary solution because we just moved in

And we need internet

[pale hawk]

VF Homebox? You mean the GigaCube right?

[hexed skiff]

Yes

[pale hawk]

Yeah, those are NATted. No possibility to fix that.

Or VF lets you use APN web.vodafone.de

[hexed skiff]

Echt? Nichts was man dagegen tun kann?

[pale hawk]

Nein. VF bietet bei GigaCubes - soweit ich informiert bin - keine Möglichkeit zum Ändern des NAT Typen bei der APN home.vodafone.de. Das können die nur bei web.vodafone.de und bei Handyverträgen.

[hexed skiff]

Sehr sehr schade ich habe mich echt auf Splatoon gefreut hahaha

[pale hawk]

Bei o2 wäre es gegangen. o2 hätte die Möglichkeit.

[hexed skiff]

Ich bin seit 7 Tagen dabei dieses problem irgendwie zu beheben immerhin hast du mir jz eine endgültige Antwort dafür gegeben.

[pale hawk]

Bekommst du VF Kabel oder DSL später?

[hexed skiff]

Keins von beiden wenn wir wieder einen festen Wohnsitz haben kriege ich meinen alten o2 wlan Router wieder

Wir sind in einer Übergangswohnung deswegen auch diese vf kiste

[pale hawk]

Du meintest dass der GigaCube nur temporär wäre. Also kommt noch ein Festnetz-Anschluss?

[hexed skiff]

Ganz genau

[pale hawk]

Der wäre wo?

Auch VF?

[hexed skiff]

Ne o2 voraussichtlich das haben wir all die Jahre benutzt

[pale hawk]

Das passt. o2 würde das fixen. Kann ich dir als o2 Kunde sagen ^^

[hexed skiff]

Haha ja trotzdem vielen lieben Dank dann brauche ich mir ja keine weiteren Mühen mehr machen.

[pale hawk]

Na ja, du könntest den GigaCube brücken.

[hexed skiff]

Ist halt schade das der ganze Aufwand umsonst war

[pale hawk]

Eine VPN würde das mit der NAT beim GigaCube fixen.

[hexed skiff]

Ahhh ja das habe ich auch als mögliche Lösung gesehen

Kosten vpns nicht meistens Geld?

[pale hawk]

Weiß aber nicht ob das Sinn macht. Weiß nicht wann o2 dich aufschaltet?

[hexed skiff]

Ach das dauert noch wie gesagt erst wenn wir in unserer neuen Wohnung sind

[pale hawk]

Ok. Und ja, VPNs kosten Geld. Und du musst ne Möglichkeit haben das zu brücken. Ka ob du das hast...

Also ich persönlich hätte auf den Anschluss von o2 gewartet.

[hexed skiff]

Mhmmm verstehe verstehe

Ist sowas denn kompliziert

Den Router zu „brücken“

[pale hawk]

Brauchst halt ein Zweitrouter der die VPN-Verbindung aufbaut. Sowas können in der Regel DD-WRT und OpenWRT router.

Oder gerootete Handys.

Ansonsten wird's schwer.

Weil ich gehe mal davon aus, dass du diesen Huawei VF Gigacube hast oder?

Hatte diese lange nicht mehr aber ich glaube, die konnten keine VPN herstellen.

[hexed skiff]

Ach das klingt ja tatsächlich ziemlich kompliziert hahaha

Ja ne dann lasse ich das ganze das einzige was ich jetzt noch versuchen könnte wäre das wlan vom Nachbarn anzuzapfen 🤣🤣

Die haben mir am Anfang auch mit Freude ausgeholfen 👍🏾

[pale hawk]

Und dann darf es nicht Vodafone DSL sein xD

Weil die NATten auch und dann haste wieder 220.

[hexed skiff]

Du scheinst dich ja ziemlich auszukennen

Woher hast du das ganze wissen bist du Informatiker

Oder etwas in der Art

[pale hawk]

Bei der Bundeswehr 😛

Also IT-Admin bei der Bundeswehr

Befasse mich schon lang damit, ja xD

[hexed skiff]

Ach tatsächlich viele von meinen Freunden gehen zu Bundeswehr im Moment

Na das ist ja mal was

[pale hawk]

Ja gut, dann wird o2 wahrscheinlich dein Problem lösen mit der NAT. Kannst es aber nochmal testen mit der Wii U und schauen ob die 120 anzeigt.

Weil mit dem Support Code 120 kann man online spielen.

[hexed skiff]

Also ich habe mich jetzt mit dem wlan von den Nachbarn verbunden und es hat sofort geklappt ohne Probleme

Ist jetzt auch keine dauerhafte Lösung da die einen Stock unter mir sind aber das hat mir schon sehr weiter geholfen

[pale hawk]

Top, viel Spaß ^^ und hoffe, dass o2 dich schnell aufschaltet.

[hexed skiff]

Danke dir 🤩👍🏾

[slim lantern]

Rule 8 btw sorry

[sacred dock]

It says please so it's just a friendly request /jk

[slim lantern]

No it’s a rule

[limber scaffold]

You cant speak German here

only English

[slim lantern]

Yes

[next nacelle]

quick question! how are you able to reproduce the D/strict type, and are you able to get switch type C at all? I was able to get A and B fairly easily but not the others

like, what router settings did you use? I know they'll vary on manufacturer but it should at least give me a hint

[obsidian current]

Have you tried a mobile data network?

I believe they left the server a week or so ago so you'd need to DM them about it

I'm able to actively reproduce D usually through O2, I don't know whether I'm likely to get C but I have an assortment of eSIMs I could try

[limber scaffold]

I am DMing them rn

[obsidian current]

I may as well copy this over, since I'm not entirely sure whether it's related to Ethernet/LAN or WiFi

Got -00 on a type B Virgin Media FTTP WiFi connection and -01 on a type D O2 - UK 4G B1+8 connection

https://forum.pretendo.network/t/off-topic-stuff/2281/1227?u=gamersinternatio

[obsidian current]

You can get F???

[limber scaffold]

NAT F means strict NAT

[obsidian current]

Not sure how I'd actually reproduce that.

I do wonder whether I could use VMware and a USB WiFi adapter to potentially test some combinations too, I've never really messed around with the configurations but I believe you can set max speeds and delays but not sure about anything else.

[next nacelle]

I got B on both Optus and Telstra on iPhone hotspots

maybe iOS is doing some magic, idk, or it's because the australian networks are v6-only so are NAT64ing (which looks like a normal NAT to a v4 client)

[obsidian current]

imagine Australian networks being good for once

O2 is completely IPv4 for me apart from IMS (essentially 4G or WiFi calling), same for Virgin Media

Host-only or LAN segment sounds interesting, will try passing through my USB WiFi adapter when I get chance in a Windows 10 VM

Might not give out any new information, but it doesn't hurt to experiment with different conditions

https://medium.com/@danielalmeidarj01/vmware-workstation-network-adapter-settings-86471397b8eb

[slim lantern]

Thought you said you use iiNet bruh

[next nacelle]

LAN and mobile hotspots are different things ya silly

[obsidian current]

I'll see if I can grab some more information about NAT types anyways.

Going to see if I can get type C from 3 eSIMs: Seeek (3 AT host, currently have it set roaming to EE on probably B20+7+7 or B3+3), Firsty (KPN NL, set to roaming on EE on the same bands) and bneSIM (Play PL, set to roaming on Vodafone on B1+7+20) and I'm going to test a scenario with a local only connection

[obsidian current]

Can confirm 220-01 again on NAT type D

Wonder whether it's worth mentioning that it's open, I haven't tried putting a password on to see whether it would change what the second number says

Still 220-01 on WPA2, good to know

Changed SSID to NintendoSpotPass1 for testing but nothing different, time to try turning radios off

003-2002 if it can't connect to internet

Will mess with my eSIMs now

EE on Firsty seems to give my Switch nothing whatsoever but I'm wondering whether it's because it's 0.1mbps and it just can't do anything (although saying that, I can still use Discord fine on it)

Might have something blocking it from tethering

[limber scaffold]

Is this connection 3?

[obsidian current]

got type C

[obsidian current]

Connection 2

220-00 on type C

[limber scaffold]

okay, i am assuming 003-2001 for connection 1

[dawn bridge]

003-2001 (3DS/2DS)

Support code detected, press to expand information

[limber scaffold]

and 003-2003 for connection 3

you could try

Could be useful info for Bandwidth

[obsidian current]

Red Bull Mobile got me there, A1 AT

Will try with my other eSIMs, not convinced that 220-00 = type C yet but it doesn't hurt trying

I'm wondering whether the 2 at the start etc might depend on the connection number, I'm going to test that quickly

[limber scaffold]

I have just 1 eSIM

let me try

[obsidian current]

Tried on connection 3, still 220-00

[limber scaffold]

003-2102 should mean DNS fail?

003-2101

[dawn bridge]

003-2101 (3DS/2DS)

Support code detected, press to expand information

[obsidian current]

Yeah, I think I got that on Firsty

[limber scaffold]

I got 000-99

Connection 1

[obsidian current]

Never seen that one before

120-00 on Seeek, guessing type B

[limber scaffold]

Let me try my Switch then

[obsidian current]

Yep, type B

man the speeds on EE are real slow lol, 161.8/19.5kbps according to my Switch

[limber scaffold]

I got NAT F

on Switch

[obsidian current]

Oh god, I'm guessing that's NAT type F then with that code

Got 220-01 on bneSIM, NAT type D on Switch

[limber scaffold]

No wonder why I get 86420 if I try on phone

When I play DS games

[obsidian current]

I assume DS is different?

I have no way to test type A but I can try

[limber scaffold]

When I try to matchmake to trade in Pokémon I get error code 86420 if I don't use my PC

For hotspot

86420 means strict NAT

[obsidian current]

I'm going to try hotspotting using Windscribe app on desktop and see if anything changes

Might need a few minutes to set it up

oh ermm it's on 5GHz

I'm not sure how to avoid that from happening, I can try the dongle I guess

i also just happened to find the drive i wanted to use for using dumpling which is nice lol

i lost it and didn't know where it went

and I can't see the dongle which I wanted to use

Not exactly sure how to get this to work, but going to mess with device manager to get it to 2.4GHz, seems to be WiFi Direct

lol it gave up as soon as I put my laptop on 802.11a (WiFi 1?)

finally on 2.4GHz, I've never seen something on -23dBm

120-00, same as normal WiFi, will try some of the restrict NAT and circumvent censorship options

apparently still on type B even with this option turned off but my 3DS failed the test (Switch worked)

tested with a proxy as well from a random website, code doesn't change, i reckon its just nat type

cant see anything else to try honestly, going to publish information

now i gotta remember to set to wifi 5 again instead of 3? (g)

I'm going to publish it right now until something else pops up since having information out there will help someone I'm sure

[pale hawk]

So I see you all were experimenting with the support codes and NAT types? xD

[limber scaffold]

Welcome back

[slim lantern]

I already have this you know

220: C, D, E, F
120: B (Mobile Hotspot)
110: B (Residential Network)
100: A
XXX-00: Wireless
XXX-01: Wired

[pale hawk]

I have never seen 100- tho.

For me it's 110 or 112 Type A.

And idk why you separate B Mobile and fixed.

[limber scaffold]

My NAT F is 000-99

iliad mobile hotspot

[slim lantern]

quarky tested

[slim lantern]

ookay

[pale hawk]

iPhones are exposing their clients. It's equivalent to NAT Type A what you get on iPhone hotspots. That's what my Switch gets on a iPhone hotspot and public PDN.

I haven't tested it with a restricted PDN tho.

[pale hawk]

Maybe you can also that chart from Nintendo. To understand it, it shows for example that Strict NAT players can only play with Open NAT players (A).

[obsidian current]

wb

[obsidian current]

110 isn't B on a residential network, I have 120-00 on Virgin Media

I don't think the numbers at the end indicate wireless or wired either, I was testing on a 3DS and as an example, type C was 220-00 and type D was 220-01

[slim lantern]

idek anymore

[obsidian current]

I don't think xx2-xx necessarily means it's using Ethernet either currently, I think @next nacelle tested it on a mobile hotspot and they were getting 122-00

Could it be NAT64 translation? #1279073049550782479 message

You didn't have to delete it lol, I just don't think it necessarily indicates Ethernet at the moment

[obsidian current]

ermmm i just got 120-02

i just enabled a oort triggering thing and that happened because i can only port forward on one device?

I'll check my Switch rq as I was messing with getting type A earlier

My Switch shows A, interesting. I disabled the port forwarding on my Switch

I'm confused now lol

hang on nvm, 3DS is getting 110-00 now

I wonder what 120-02 would actually mean?

It seems as if it's 110-00 if my Switch isn't online and 120-02 if it is online

I don't know how to test this in this case

My Switch seems to remain on A still, I'm not sure honestly

@pale hawk any ideas?

I'm not sure honestly why that happened and I don't know whether I can accurately reproduce

Got 110-02 now too? Don't have a clue

[midnight jackal]

What NAT are you trying to reproduce

[obsidian current]

I was hoping for type A (which that screenshot was) but I have no idea what the -02 means. Tried enabling port filtering to get me to type A

[midnight jackal]

02 usually means that its limited to a certain amount of data. This usually happens on my mobile hotspot and to alot of otbers

I dont get how the wii u can detect it

[obsidian current]

A certain amount of data? That's odd considering it's on a Virgin Media Hub 3 and I don't think my phone can reproduce since it doesn't identify as a hotspot iirc

[midnight jackal]

Switch to Mobile Data and setup hotspot on an android device

[obsidian current]

I've done so already, 120-00 on my home broadband and it would be 220-01 on data

[midnight jackal]

Yes, it has to be non apple due to apple hotpots having OpenNAT

[midnight jackal]

I could try force replicating it, Any thoughts on what it could be?

[obsidian current]

Not sure honestly, since port filtering and a custom IP reservation (to 192.168.0.211) was the only modifications I had on

[midnight jackal]

Try turning off one of those, like IP Reserve

[obsidian current]

@next nacelle also, do you have any idea what ports Pretendo happens to use for P2P? I'm planning on adding advice from the official Nintendo website to the FAQ to improve NAT type since I know 1024-65535 definitely works but I wonder if the range can be reduced?

[obsidian current]

lol top result of Bing

[next nacelle]

most nex games just choose at random unfortunately. I was investigating the possibility of fixing the port number but nothing is ready with that yet

[obsidian current]

Yeah, thought that might be the case, thanks for clarifying 👍

[wild wolf]

I have reported this issue tons of times here and on GitHub (mostly on this server) and the only response I got was Jon blaming my internet (kinda true sadly) but even if my NAT is strict, my mobile data network supports UPnP (checked by Wiimmfi's UPnP feature when you search a match online in Mario kart Wii), and I was able to perfectly play online Splatoon 2/3 on the Nintendo switch with this same connection. I hope they fix this issue in a future

It reached the point where if I miraculously join a room and the match starts, I get kicked mid game and then kicked again from the lobby with the "no internet connection" error code.

[next nacelle]

nex games on wiiu don't even attempt to use upnp or nat-pmp unfortunately.

it's kinda a hard problem

if you succesfully make it into a room then NAT is unlikely to be the issue

[wild wolf]

Maybe my NAT is just strict and in the times I was able to join a room, the host was NAT type A

[obsidian current]

Can you check your NAT type for me?

https://forum.pretendo.network/t/guide-detecting-your-nat-type-on-wii-u-and-3ds-consoles/6159/

[wild wolf]

In some hours I can
I am at work rn

[wild wolf]

@obsidian current @next nacelle I made the NAT test
I will explain my setup 1st
I have a 4G router that is capable of doing port forwarding, DMZ and UPnP (it can also do VPN but its ancient and most modern VPNs doesn't support the router's protocols anymore
And my mobile carrier has two different kind of public IP addresses you can get which are different in terms of P2P
One type of public IP address I can get is 100.xxx.xxx.xxx which doesn't support UPnP neither can do p2p properly, but it can still do it with Nat type A ones
And the second one is 10.xxx.xxx.xxx which does support UPnP and can do p2p better
How do I know this?
I tested both IP addresses on Nintendo switch, the 100 one gave me NAT type C no matter if you enabled DMZ or port forwarding while the 10 one gave me NAT type B and type A with DMZ / PF enabled.

Now, I get this support code with the 100 IP address

On the 10 one I get this:

It seems that my support codes aren't on your forum guide which is interesting

[obsidian current]

Interesting, possibly type C?

[wild wolf]

Its close so maybe yes?

I will re do connection test, maybe I can get different codes

I got 210-01 with the 10.xxx IP address, maybe both 10 and 100 are the same in this situation

Yup, no matter what IP address I'm on, I will always get both 210-00 and 210-01

[young sorrel]

ye

[mortal berry]

have u tried turning upnp on in ur router?

[slim lantern]

?

[solar citrus]

Sorry for coming in on a dead thread, but are we really sure that 000-99 means NAT type F? My Wii U has no problem playing online, but reports that code on the connection test. My 3DS and Switch indicate NAT type B on the exact same network, again, with no problems playing online. NAT type F may cause this code to appear, but this code clearly isn't exclusive to people with bad NAT either.

[wild wolf]

I can say that the NAT measuring method isn't much accurate

[wild wolf]

Your NAT is fine
You can even open it (Type A) for better p2p room stability (specially when you become the host)

Now that pretendo only uses 1 port for matchmaking/gameplay, you just need to open that port specifically

[next nacelle]

note this is only true for specific games

[wild wolf]

I know, the main games

[wild wolf]

Hey @next nacelle idk if its already possible to do it, but I would like to be able to specify which port pretendo will use to do matchmaking/gameplay (kinda like you can do on Wiimmfi for Mario kart Wii). So I can organize my port forwarding configs better

Is it possible to implement?

For example I want pretendo to use port 18352 for matchmaking

[next nacelle]

yeah I guess this is possible. we figured it was more conveninent to Just Pick Something but if you want to override it

[waxen ferry]

cant play onile bc i got nat type d

im trying to change it but its too impossible

[crimson sinew]

True 😭

[peak veldt]

My support code is 2200 - 01, idk how to change it so i can play online. Cause when i get to the lobby in splatoon and mk8 I always get the same error

118-0502

[dawn bridge]

118-0502 (Wii U)

Support code detected, press to expand information

[peak veldt]

but i can play mario maker perfectly fine

[obsidian current]

What kind of connection are you playing on?

[obsidian current]

Mario Maker does not rely on peer to peer networking

[peak veldt]

Wireless

[obsidian current]

sorry I could have clarified better, are you using something like Starlink, a fixed line ISP or mobile internet

[peak veldt]

No but a VPN

[obsidian current]

that VPN might not be helping you. is there a chance you can try playing online without the VPN?

[peak veldt]

I will try
