I think it's easy to port forward on any router . ( You must port forward to router and ur PC)
press Start ---> My Network Places---> Local Area connection,right click--->Advanced--->Settings--->Firewall-->Advanced--->Settings and there u can add your ports. ( TCP-22005, UDP-22003 , UDP -22126 ) and for router type 192.168.1.1 and got o NAT, or Virtual Servers . add same ports there too . that should enable your ports . In console type "openports" and check if the ports are open .
