Potential Port Forwarding Issue (maybe CGNAT?)
I'm creating a 1.20.1 forge server with ~70 mods for some of my friends. However, whenever I try to connect to it via my external IP address (I think that's what it's called) most of the time I connection time out, and only occasionally successfully connect. I've checked my portforwarding through https://canyouseeme.org/ and it comes back valid. Connecting to the server via the local device IP address works so that's why I'm inclined to believe it's a portforwarding issue. Looked into it a bit and I don't believe I suffer from CGNAT with my ISP (AT&T Fiber). The IPv4 address from my router configuration interface matches the public ip on https://whatismyipaddress.com/ and it doesn't fall into any of the CGNAT ranges. Previously, I have hosted forge servers on this computer with my last ISP (Xfinity), but that was cable instead of fiber, not sure if that would have any impact at all.
Looking for any troubleshooting techniques / solutions
