Firewalls

[David Friedman <dif () ix netcom com>]

Has anyone done a comparison of some of the proprietary firewall boxes 
(Watchguard, SonicWall) versus FW-1, Gauntlet or Secure Computing's 
Firewall for NT.

Additionally, has anyone done any comparisons to NT based firewalls to 
Linux, and / or UNIX based firewalls.

My biggest concern is not leaving any holes that an outsider (or insider 
for that matter) might exploit to break in.

Thanks in advance,

David
