I forwarded the ports 23073 and 23083 and i can get a server up and running..i give my friends the ip to connect to from
www.whatismyip.com and then they try and connect but only one and some times two manage to join the game.But i can see that the others are requesting game because its showing up in the dedicated server.
Also i don't know why but the Soldat Connection Tester failed all the tests on my ports even though i forwarded them and set up a static ip..
