I use Tiny Personal Firewall, which is excellent. I think it's gone pay now, but the old version (I use 2.0.15, Oct 2001) is great and very configurable. You can set up all sorts of rules for different applications, ports, address ranges etc. Have a look for it; there are still some places offering the old version for download.
