Hi everyone, Currently I have an older version of ZAP on my Windows XP system. I would like to compare from ZAP to 8signs to BlackIce to Tiny to Kerio and so on to help me pick another firewall. Out of those firewalls I listed, what are the differences? Are they easy, medium or hard to configure the options? What is an IDS? I would like to look for another firewall with some help from this forum. I got ZAP from my Uncle. This time I am getting a firewall on my own and I would like it to be freeware. Thank you everyone for any replies to help me with a firewall.
