Alright, pulling you here to keep discussions cleaner

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.

Do you have more than one router in your home?

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

The very next step for you is to call your ISP and ask them nicely to enable you to use port-forwarding, most commonly by not putting you behind CG-NAT. 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.
