David: I have looked for a good packet-filtering firewall for Windows similar to the products that are available within many of the UNIX operating systems (e.g. IP-Filter). I prefer to setup packet-filtering rules based on service port, IP, and sometimes MAC address. Unlike UNIX, packet-filtering firewalls for Windows seem to be difficult to find, especially free versions. Last year, I located a product called CHX-I. It is free for personal use, but licenses need to be purchased for Education/Business. Fortunately, I was granted a few licenses to allow for evaluation. CHX-I may not be the easiest product to setup for inexperienced users, but it does what I need it to do and seems to work very well. The firewall rules can be saved to a text file and easily imported to other workstations that are running CHX-I. I am not familiar with the Tiny Personal Firewall, but looking at their website, it seems to include many of the same features as CHX-I, so I may need to take a look at that product one of these days.
