Here is some more information, but I have to go to bed very shortly so this is all I can do this evening. I went to http://www.grc.com and ran Shields Up on the PC-Cillin firewall. It told me that some ports were stealth, others were simply closed. According to the test, it failed. Although the report also said that all connections were refused, most ports were not stealth. I disabled the PC-Cillin firewall and reinstalled Zone Alarm Pro. The I ran the Shields Up tests again... with exactly the same results. I didn't compare the results port-by-port, but it looked like the exact same results to me. On impulse, I re-enabled the PC-Cillin firewall. Neither PC-Cillin or Zone Alarm complained, and, while I have not had a chance to test yet, they appear on the surface to live together peacefully (which doesn't sound right to me, considering the problems between ZA and the last version of the PC-Cillin firewall. Apart from the overhead of running two firewalls, is there some reason to not run them together? Any suggestions?
