You can achieve similar results as Fport by right clicking and choosing connection details from the running applications menu of Sygate. Sygate uses Stateful Packet Inspection so if a packet comming in does not match up with a request in the state table then its silently dropped any way. No need for advanced rules unless you are going to allow certain traffic through and want it to follow your specifications.

NetBIOS protection will protect any probes comming in from outside your gateway to all related ports (UDP ports 88, 137,138 and TCP ports 135,139,445,1026). If you have and do not trust your other LAN computers you can disable the ability of others to share your files from the Network Neighborhood tab and/or setup MAC address filtering.

Test your computers configuration if its acting as its own gateway with a web based portscan to get an idea what if any changes need to be made.
