Hello, I'm trying to portforward as UPnP is not working with this application. The port is 30000. On my network, I have both modem and router, the router is setup as a wifi router and not an accesspoint. Please let me know how I can do this.

#

The application using the port is allowed both public and private in the firewall. the port in question is allowed in inbound rules.

#

Quick question, the router app is asking me for service type for my port forwarding, I have it set to HTTP right now, is that fine?

It would help to know what you are trying to expose?
Are you behind CGNAT for example? Because then port forwarding does nothing for you.
If you have a port opened and you need to check if it's actually reachable try canyouseeme.org

Its an application called foundryVTT, the UPnP services were not working, so I am trying to get port forwarding to work

I checked and it says timed out

#

I don't know what CGNAT is

#

Nvm I googled it

#

How do I find out if I am behind a CGNAT

#

Do I just call my isp?

#

@lapis ravine

#

I don't know what this means

#

oh in your router set your PC as a static IP .
in your router set the port forward 30000 to your static ip

plush jetty Jan 7, 2023, 1:06 PM

#

Alright

clear beacon Jan 7, 2023, 1:06 PM

#

save configuration and restart the router (power cycle)

plush jetty Jan 7, 2023, 1:06 PM

#

The router or the pc

#

Aight

clear beacon Jan 7, 2023, 1:07 PM

#

standard routers come with a firewall

plush jetty Jan 7, 2023, 1:07 PM

#

clear beacon 1. oh in your router set your PC as a static IP . 2. in your router set the port...

Address reservation?

pic?

plush jetty Jan 7, 2023, 1:07 PM

#

Or is this something else?

clear beacon Jan 7, 2023, 1:07 PM

#

screenshot

plush jetty Jan 7, 2023, 1:08 PM

#

clear beacon Jan 7, 2023, 1:08 PM

#

should be correct

plush jetty Jan 7, 2023, 1:08 PM

#

Ok

#

@clear beacon

clear beacon Jan 7, 2023, 1:08 PM

#

this would assign your PC when it connects to the same IP everytime you boot up

plush jetty Jan 7, 2023, 1:09 PM

#

restart the router?

clear beacon Jan 7, 2023, 1:09 PM

#

call the servicename FoundryVTT or a recognizeable name

plush jetty Jan 7, 2023, 1:09 PM

#

Like turn all of them off and on?

plush jetty Jan 7, 2023, 1:09 PM

#

clear beacon call the servicename FoundryVTT or a recognizeable name

Ok

clear beacon Jan 7, 2023, 1:09 PM

#

" All of them off? " whats that?

#

be specific

plush jetty Jan 7, 2023, 1:09 PM

#

router restart

clear beacon Jan 7, 2023, 1:10 PM

#

just power cycle the router after

plush jetty Jan 7, 2023, 1:10 PM

#

what's a powercycle

clear beacon Jan 7, 2023, 1:10 PM

#

oh plug power out of the router

plush jetty Jan 7, 2023, 1:10 PM

#

Aight

clear beacon Jan 7, 2023, 1:10 PM

#

and reconnect it after 30 seconds

#

After this , when you are back start the foundry service.

#

and in the end, you could reach it using your external ip + Port so like SomeIP:30000

plush jetty Jan 7, 2023, 1:13 PM

#

Ima check on canyiuseeme.org firat

clear beacon Jan 7, 2023, 1:14 PM

#

well without the foundry service being started

#

it wont show

plush jetty Jan 7, 2023, 1:15 PM

#

Ok

#

clear beacon Jan 7, 2023, 1:16 PM

#

well did you try to connect to external port?

plush jetty Jan 7, 2023, 1:17 PM

#

Yes

clear beacon Jan 7, 2023, 1:17 PM

#

is the service running?

#

is your local port correct?

plush jetty Jan 7, 2023, 1:17 PM

#

Yes

#

website saying not working either

plush jetty Jan 7, 2023, 1:17 PM

#

clear beacon is your local port correct?

local port as in?

clear beacon Jan 7, 2023, 1:18 PM

#

The computer which is running should be running on the local IP

plush jetty Jan 7, 2023, 1:18 PM

#

Yeah

clear beacon Jan 7, 2023, 1:18 PM

#

is your pc currently having the same IP? as itr should be?

#

like 192.168.68.109?

plush jetty Jan 7, 2023, 1:19 PM

#

I don't know how to check so here's ipconfig

clear beacon Jan 7, 2023, 1:19 PM

#

that seems correct

#

also did you try to run foundry vtt with just the internal IP? did that work?

#

and connect to it using the internal IP?

plush jetty Jan 7, 2023, 1:20 PM

#

What do you mean

clear beacon Jan 7, 2023, 1:20 PM

#

(check if Foundry is UP )

plush jetty Jan 7, 2023, 1:20 PM

#

just go to this site?

clear beacon Jan 7, 2023, 1:20 PM

#

no

plush jetty Jan 7, 2023, 1:20 PM

#

http://58.65.212.37/

clear beacon Jan 7, 2023, 1:21 PM

#

as in go to your local IP and connect using the local IP to foundry

#

the 192.168.68.109:30000 IP

#

does that work?

#

if that works , we know Foundry is running

plush jetty Jan 7, 2023, 1:21 PM

#

Yup

#

it works

#

It brings me to the session screen

clear beacon Jan 7, 2023, 1:22 PM

#

Great, now we just need to make sure the port forwarding is working.

#

is the port forwarding Rule active?

plush jetty Jan 7, 2023, 1:22 PM

#

It says yes

clear beacon Jan 7, 2023, 1:24 PM

#

well try disabling windows firewall

#

just for testing purposes

plush jetty Jan 7, 2023, 1:24 PM

#

Alright

clear beacon Jan 7, 2023, 1:24 PM

#

and retry the test to see if the port is open

plush jetty Jan 7, 2023, 1:26 PM

#

Didn'twork

#

clear beacon Jan 7, 2023, 1:27 PM

#

restart PC?

plush jetty Jan 7, 2023, 1:27 PM

#

Ok

clear beacon Jan 7, 2023, 1:27 PM

#

Trying to eliminate most of the possibilities, since I tried this before on a factorio server also required port forwarding. sofar you are doing all things correctly. It takes some time before port forwarding becomes effective. ( Router being weird)

#

sometimes it take sometime for Port forwarding to be effective

#

I usually try to add port triggering as well on the same port

#

like port triggering on port 30000 if you can find it.

#

(router part)

plush jetty Jan 7, 2023, 1:29 PM

#

Didn't owrk

clear beacon Jan 7, 2023, 1:30 PM

#

add port triggering on the router as well

#

on port 30000

#

should be a simple setting

plush jetty Jan 7, 2023, 1:31 PM

#

Welp

clear beacon Jan 7, 2023, 1:31 PM

#

Welp?

plush jetty Jan 7, 2023, 1:31 PM

#

Asked someone else about this

#

He's saying I am behond the uhh

#

CGNAT

#

So I have to call my isp to have them enable portforwarding now

clear beacon Jan 7, 2023, 1:32 PM

#

well I would first try port triggering

#

since its something you can do

#

after that if it doessnt work you can always call your ISP

plush jetty Jan 7, 2023, 1:33 PM

#

Didn't work

clear beacon Jan 7, 2023, 1:33 PM

#

well restart router after

#

"Carrier-grade NAT usually prevents the ISP customers from using port forwarding, because the network address translation (NAT) is usually implemented by mapping ports of the NAT devices in the network to other ports in the external interface."

Me: " Really? , ISP use this?"

plush jetty Jan 7, 2023, 1:34 PM

#

Dunno

#

But meh

#

WAiting on my router to restart now

#

Calling my ISP is gonna be pain

#

Didn't work

#

welp

clear beacon Jan 7, 2023, 1:38 PM

#

Ok , so your behind CGNAT

#

Good luck calling ISP.

#

I did everything that should work to activate a port forwarding

plush jetty Jan 7, 2023, 1:38 PM

#

Yeah

#

Thanks for your help

#

But meh

clear beacon Jan 7, 2023, 1:38 PM

#

yeah understandable

plush jetty Jan 7, 2023, 1:38 PM

#

I doubt they'll accept this request considering I live in a fairly urban area

clear beacon Jan 7, 2023, 1:38 PM

#

good luck making that Service desk employee understand

plush jetty Jan 7, 2023, 1:38 PM

#

Kek

clear beacon Jan 7, 2023, 1:39 PM

#

Usually they are students

#

with basic knowledge

plush jetty Jan 7, 2023, 1:39 PM

#

seriously?

clear beacon Jan 7, 2023, 1:39 PM

#

🤷‍♂️ thats why I dont like calling ISP's

#

Well since you are a customer, they should help you with your request

#

Otherwise its time to transfer to another ISP

plush jetty Jan 7, 2023, 1:40 PM

#

Probably

#

And they are closed

#

they open monday

#

Bruh

clear beacon Jan 7, 2023, 1:41 PM

#

well we used table top simulator before

#

let me connect you as friend on discord

#

Ill add you to another discord with allot of Table top people

#

they might have alternatives, allot of GM's are on there.

#

and games you could join if you want to

plush jetty Jan 7, 2023, 1:42 PM

plush jetty Jan 7, 2023, 1:43 PM

#

All my players probably can't afford the 20 dollars for tabletop sim

#

I got foundry because uhh

#

It meant only I had to buy it

#

and I'm basically paying for 10 months roll 20, for an account I can use for years

clear beacon Jan 7, 2023, 1:44 PM

#

That is fine, but they know the tools more as I do and can recommend you decent tools

plush jetty Jan 7, 2023, 1:44 PM

#

plush jetty Jan 7, 2023, 1:44 PM

#

Well, thanks

clear beacon Jan 7, 2023, 1:45 PM

#

They also play multiplayer games online as well , for table top games

#

and it doessnt hurt to look around and ask 🤷‍♂️
