Linux Firewalls
I've been considering switching my companies production firewall from FreeBSD and OpenBSD to Linux. The reason being is having so many different flavors of Unix on our production network from FreeBSD, OpenBSD, Solaris, and Linux makes things more difficult to manage from a standardized perspective. I really like OpenBSD firewalls. The os is clean, the code is tight, very small, and very secure. But having one flavor of Unix (namely Linux) would make things a lot simpler to manage. I've also been considering other firewalls from Cisco and Checkpoint (I think I'll stay away from Raptor). I wanted to know everyones opinions about using Linux for a commercial firewall in a corporate/production environment. If anyone out there uses it, has comments, suggestions, or bad experiences, I could really use the input from other admins. Thanks.
