hey if you are going non hamachi you need to do some network mods, firstly add your internal ip-subnet and default gateway in your IP4 network settings then hit the advanced tab on the same dialog box and add your external (whats my ip) ip address and then you should be able to bring up the server
i almost forgot to add a couple things- Some of the new servers from chinese use new ports
-instead of 5816 -- 58888
-instead of 8653 -- 18653
and this is what ip goes where-
127.0.0.1 only is used for server connection
internet-game&Acc server ip's are your external or hamachi
Hope this helps
