1. The article in your link is almost 3 and a half years old "Updated 3/25/2002 8:23AM" and firewalls have advanced greatly in that time and most pass the GRC leaktest and the many other leak tests.
Its 3 years ago?
But it seem to be able to trespass all the famous firewall ZA6, outpost 2.6
Only component controls can help here, well , until now, i suppose Kerio 4 is the only one to offer component control?
You have got to be joking, the article is talking about a vulnerability (leak test, component checking) that is well and truly catered for in the latest mainstream browsers.
As for "But it seem to be able to trespass all the famous firewall ZA6, outpost 2.6" what, the article or leak test, rubbish I have had many different firewalls that all passed the GRC leak test, this includes earlier versions of ZA, Outpost 1.0 (freeware version) and Outpost Pro 2.7.
Outpost Pro is widely acknowledged as having one of the best component control out there.
You are wrong in your supposition that Kerio 4 is the only one to offer component control, most of the mainstream firewalls do.
