To be honest two people said the same thing, and 3 others are just completely wrong. Invalid protocol posted the fix had anyone bothered to investigate the link.

block outbound TCP to 27017, 27018, and 27019.

With multiple IP allocations the server falls back to TCP, if you block them, it reverts to UDP. It has nothing to do with his +ip vs -ip configuration.

You can launch the program with a special group ID and then configure IPTables to filter on the group.

Unless things have changed, this doesn't help. Your listening port is bound to the IP you specify, but the master server lists you on the IP your traffic to it comes in on, and since the servers on Linux do NOT bind outgoing connections to your chosen interface, that means it always uses the default route and your primary IP.

The master server doesn't take your word for good reasons; you could be behind NAT, for instance. the server not binding outgoing connections to your chosen IP is a bug.

What that guy below said. You need to use -ip on the command line, NOT +ip.

I'm pretty sure the reported public IP is the one that Steam sees your
packets coming from, and the other address it the one the game server is
bound to.

Can you connect to your server via the eth0 address; 85.x.x.57:27015? If
not then there's nothing to worry about. Also I don't know why you've
hidden your IP, when it's publically available on the master servers ;)


Kind regards,

Hello,

I have discovered a strange thing with our DOD:S and TF2 servers today.
Take a look at the line of the status output:

udp/ip : 85.x.x.95:27015 (public ip: 85.x.x.57)

We are binding our server to 85.x.x.95 with +ip as start parameters. The public IP shows our IP address from the first network card eth0. Wtf? How
can I prevent this behaviour?

Best regards

Ronny
