  • Ports

    v1 v2  
     17dtd uses several ports to allow for its functionality. By default these are
     2||= Port =||= Default =||= Protocol =||= Direction =||= Used for =||
     3|| BasePort || 25000 || UDP || In || Game ||
     4|| BasePort+1 || 25001 || UDP || In || Game ||
     5|| BasePort+2 || 25002 || UDP || In || Game ||
     6|| WebControlPort || 8080 || TCP || In || Web based control panel ||
     7|| TelnetPort || 8081 || TCP || In || Telnet control ||
     8|| 270xx || || UDP || Out || Registering at the server list ||
     9
     10  WebControlPort / TelnetPort::
     11    Only if enabled in serverconfig.
     12  270xx::
     13    Should be in the range 27015 - 27030 according to [https://support.steampowered.com/kb_article.php?ref=8571-GLVN-8711&l=english Valve]. But as others have been reported too I would simply suggest opening 27000 up to 27050 here.

     15If you have a firewall set up that blocks all traffic by default you have to open at least the Game ports (default 25000 - 25001). If you also want the server to be listed on the server list the 270xx ports have also to be opened. ''iptables'' rules for this could look like this:
     16{{{
     17iptables -A OUTPUT -s <yourServerIp>/32 -p udp --dport 27000:27099 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT
     18iptables -A INPUT  -d <yourServerIp>/32 -p udp --sport 27000:27099 -m state --state RELATED,ESTABLISHED     -j ACCEPT
     19iptables -A INPUT  -d <yourServerIp>/32 -p udp --dport 25000:25002 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT
     20iptables -A OUTPUT -s <yourServerIp>/32 -p udp --sport 25000:25002 -m state --state RELATED,ESTABLISHED     -j ACCEPT
     21}}}

     24== Protecting the Telnet interface ==
     25
    126Opening the 7dtd Telnet port to the whole internet may pose security issues as the connection has no protection. The least that could happen is people doing random stuff on your 7dtd server but it could also be that attackers find security holes in the engine and gain further access to the host.
