I've been trying this aswell, just bought a router .
i used the guide in the 1.4 section but i can only get as far as the char select screen then it just fades, no notice comes up
[edit]
just fixed my problem i had
Code:
[GameGate]
Title=ktest
ServerAddr=127.0.0.1
ServerPort=5000
[color=red][b]GateAddr=0.0.0.0[/b][/color]
GatePort=7200
ShowLogLevel=2
ShowBite=1
ServerCheckTimeOut=180000
ClientSendBlockSize=500
MaxConnOfIPaddr=50
BlockMethod=0
MaxClientPacketSize=6420
NomClientPacketSize=190
MaxClientMsgCount=100
kickOverPacket=1
ClientTimeOutTime=5000
The part highlighted above i had set to 127.0.0.1 instead of 0.0.0.0
