Server browser connect not working for dedicated server

[cpy]

I'm posting it here since nobody looks at dedicated server posts and I actually might get help here, since it is technical problem.

I have server behind NAT, anyone can connect if they use direct connection to my IP (from internet), but trying to connect to server from LAN or internet via server browser does not work, but direct connection works perfectly from internet and LAN.

So if they try to connect to my server listed as CPY Industrial Revolution, it's unreachable, but direct connect to cpy.zapto.org works I think you have something broken in public server browser.

Post corresponding logs of server and client after a session with the issue.

Ok, any help with logs location for dedicated server? Oh I see your signature.

Here are the logs:

So I just tried connecting to your server, both from the server browser (which failed; the server browser also failed to establish a ping) and connecting directly to cpy.zapto.org (which managed to connect, but I don't know the password; that doesn't matter for this test; I think the logs have enough data). From my log

Note the different ports. The server browser gave me 1453 (which failed), and direct connect (without me specifying a port) gave me 34197. Could be a network configuration/routing/port forwarding issue. (Could also be caused by two servers running on the same external ip, but only one being externally reachable).

Also reminds me of viewtopic.php?f=7&t=62792#p443290 and viewtopic.php?f=49&t=73540&p=444126 .

I suggest checking what port the server is actually running on, and your routers port forwarding rules.

Ok why is the server browser getting different port? I want to set everything manually.

[Zavian]

One possible explanation. Your server is running on 34197, but your router is doing NAT on the outbound connections to the pingpong servers, and translating that to 1453, despite you having setup port forwarding for port 34197. The fix would be convincing your router not to do that.

[cpy]

I don't think router is doing this.
ServerRouter.cpp is doing this crap! (factorio code?)
My server is in DMZ.

[BlueTemplar]

I'm curious : is it possible for you to remove NAT and force IPv6 ? No port-forwarding, no problem ?

[cpy]

I can try plugging server directly to internet. I think that their stupid ass nat punch service is broken and unable to define static port is doing this.
I don't need UDP NAT punch, i need a way to set everything myself.

When i block pingpong*.factorio.com I get correct port but wrong IP in game list 10.30.49.248 (which is none of my internal IPs or anything else).

[BlueTemplar]

Just don't forget to check that your firewall is up to date and working !
NAT wasn't designed with security in mind, but AFAIK it does help somewhat ?

[cpy]

I don't use firewall, everything that does not use stupid ass udp hole punching and can be configured myself and not rely on god damn servers somewhere else works!
My webserver works, my ftp server works, mumble server works. Everything that I can set manually myself works.

I guess I need another router. Stupid Chinese Tenda crap. Never again.
