Steam – Day of Defeat Server runs but nobody can join

Preface: I was not sure if I should ask here or on serverfault but I think it is more a game issue than a server issue itself…

I have a small dedicated server rented which runs Counterstrike (1.6, not Source!) since yesterday. I used the SteamCMD tool to install everything I need and it nearly worked out of the box. (Used the steamcmd documentation)

Now I try to do the same for Day of Defeat (again, not Source) and after some struggling the server finally boots fine.

# ./hlds_run -console -game dod +maxplayers 8 -port 27016
Auto-restarting the server on crash

Protocol version 48
Exe version 1.1.2.7/Stdio (dod)
Exe build: 17:45:07 Apr 25 2013 (6027)
STEAM Auth Server
Server IP address 78.47.102.222:27016
couldn't exec listip.cfg
couldn't exec banned.cfg

The real problem is that I can't connect to my own server! I used the IP and the hostname (always with the port) and I tried to search ingame for game servers on that IP (you can do that when adding an IP/Address to favorits) but only my CS server is displayed.

I also shut down my CS instance and used the default port, still the same issue. The server always starts but I can't connect…

One thing I saw which made me wonder: the server.cfg mentions dod v1.2 but with the latest update it should be dod v1.3. Is there any way I can verify the dod version of the server?

I triple checked if there is an update missing by running the steamcmd update commands multiple times:

# ./steamcmd.sh
