[Any suggestion for a good firewall software]

Thanks for that update on sygate. I'm using the service pack 1a and cannot use the service pack 2 because i'm trying to do a research on network security and what would actually secure the entire network and not just a single computer. If i install the service pack 2 it will not let me use any network monitoring tools coz its a kernel level patch. Therefore i have to use a firewall. Any suggestions??
