Pulling this into a thread to not interfere with on-going support 🙂

If you use the local network link from a different device on the same network are you able to get to the login page? A cell-phone on wifi works great for this test.

Local network yes

#

In my phone works fine

#

but Internet no

neon ermine

Ok; that's good. Let's check if your ISP is up to no good.

Carrier Grade Network Address Translation (CGNAT)

CGNAT is a service used by ISPs to decrease the number of IPv4 addresses their networks use. It places an additional router outside the customer's own network and provides them with an internal IPv4 address provided by the company. This often prevents incoming connections on numerous ports.

Confirming the presence of CGNAT

To confirm you are affected by CG NAT, use one of the following commands:

Windows 10: open a powershell window and use the following command
tracert -h 5 (curl https://ifconfig.me/ip -UseBasicParsing); tracert 8.8.8.8

Mac/Linux: open a terminal and use the following command
traceroute -m 5 $(curl -4 ifconfig.io); traceroute 8.8.8.8

After the command has completed, please post a screenshot here with the results so a troubleshooter can interpret them.

that's it?

Please let it finish 🙂

ah ok

# cursive breach ah ok

I have bad news for you.

Your ISP has you behind CG-NAT. CG-NAT is extra layers of routers which you don't have access to, so you can't configure port forwarding on them, which means your players can not connect to your game.

The very next step for you is to call your ISP and ask them nicely to not put you behind CG-NAT or to enable you to use port-forwarding. Some ISPs just do it when asked, others want to charge money, and others refuse.

If your ISP does not cooperate:

  • Hosting option 1: Paid hosting partners do all the work, costs money - https://foundryvtt.com/article/partnerships/
  • Hosting option 2: One of your players may host your game for you, if their ISP allows port forwarding.
  • Hosting option 3: Oracle and AWS are cloud hosts with free offerings, costing effort instead of money. More details upon request.
  • If none of these are options for you, you can attempt to use VPN-like software (such as Hamachi, ZeroTier, ngrok, etc) to punch a connection through the CG-NAT, but we can not assist with any connection troubleshooting if you take this route.

hmm

#

thanks for the info

#

so

#

this port open is "fake"?

#

I had called them to open this door and they did it

minor pulsar
#

Uh, hold a moment.

neon ermine
#

If they claim it's open, it doesn't seem to be working yet or you need to manually setup port forwarding

minor pulsar
#

Get me screenshot of that edit screen for that rule.

neon ermine
#

Yeah; if that's a manual port forward rule that you've setup, then it looks like something isn't set right

#

(However, unless your ISP has specifically fixed things for you.... There's still a CG-NAT issue beyond your own router)

cursive breach
#

I don't have access for my router

#

I called them to open and this my comprovant

neon ermine
#

I don't think they set it up right.

#

Here's why:

cursive breach
#

I don't have anything else about the network, after all they don't give me access

#

:C

#

It's very bad

neon ermine
#
  1. The WAN IP address there is the shared IP address they have with multiple other customers - so this rule doesn't do anything because
  2. There is a second router infront of this one (that's the one at the second hop in your trace) that needs to hand a port forward
cursive breach
#

hmm ok

#

I will contact them to resolve this, thanks for the information

neon ermine
#

Best of luck!

@neon ermine

#

my internet provider say it fixed

#

it's ok?
