I have a Dell PowerEdge R620 on a rack downstairs that I use for all sorts of stuff including a webserver that is accessible from the outside world. I'm running Ubuntu server on it and I've updated the 7 Days dedicated server to the latest version. My server and PC are all wired ethernet with no wireless bridges between them or anything.
First and foremost, I can't seem to connect via direct IP in my own subnet. The firewall (ufw) is active and I have these rules among my others:
On the first attempts I made to connect, the server would spit out a message saying "INF NET: Rejecting connection request from 192.168.0.201: Limiting connect rate from that IP!" once in the log. The client would attempt to connect but then just time out because LiteNetLib couldn't make a connection, and Steam networking was initially disabled on the server so that would time out too, with the "Couldn't get server information" message. When I set the server to public, it would appear in the server list and this time, when I attempted to connect, I would see repeated entries like this in the server log:
Eventually I enabled Steam networking in my server settings, restarted, and this time connection would work, since Steam does its own thing to facilitate connections.
After this I tried connecting to my server again via my server's local IP address. This time I was getting repeated LiteNetLib attempts logged, which wasn't happening before.
I'm stumped, and I'm not even at the level yet where port forwarding would come into play. Why is my server not receptive to straight TCP/IP connections via LiteNetLib?
