A router would be a much better solution (http://duxcw.com/faq/ics/waysshare.htm)… With a router of SyGAte you have to setup ports that go through the NAT/firewall for games. I have repeatedly had to look-up these links and they are not easy to find, so I made an FAQ out of your question. LarrySyGate Game Configuration

Q. Where do I find information on setting-up SyGate Internet Connection Sharing (ICS) software for Internet games, online chat, personal communications, etc.?
A. All of the information I have is in Application rules Configuration Guide for Sygate Office Network and Sygate Home Network (http://www.sygate.com/support/documents/conf_sg.htm) and Using New Applications with Sygate Office Network and Sygate Home Network (http://www.sygate.com/support/documents/applications.htm). There may be more info in our Forums
