I recently bought a new router. I tried to host a server today, but I seem to have some issues with it.

First: Whatever I try, it never shows up on the master server.

Second: When I use the default port for the server (10666) and I let others manually connect (by typing connect in the console), they get stuck on connecting, however I do see some weird messages in the console, of which I have no idea what they mean, I haven't tried today so I don't know the exact message atm, will post that later.

When I bind my server to port 80 (which I normally use for my webserver), connecting manually works fine somehow, but it still doesn't show up on the master list :(.

Does anyone maybe know how to solve this and how to get my server on the master server list?

Try opening ports 15300 as well in addition to 10666, check to see that it's actually trying to use port 10666. See if UD*P or whatever its called is used (I forget it, its like U something something P) if all else fails.

Use a program to see if a port is open (I use Soulseek, for some reason other port programs don't seem to work).

This is weird, port 10666 seems closed indeed. I tried this service to check it: http://www.ipfingerprints.com/portscan.php

When I use port 80 it says that it's opened but when I full in 10666 it says it's closed, even though I have the exact same rules in my router settings (different port numbers of course). Same goes with 15300.

Somehow, I can't seem to open any port besides port 80?
Anyone has any idea of what might be going on here?

EDIT: Never mind, I used a proper port checker, and confirmed that all ports are open. Apparently opening port 15300 did the trick. Last time I was hosting servers just opening port 10666 was enough. Oh well, thanks for the help!
