OT: Firewall running OpenBSD, why?

Let me address the last paragraph first by stating I've been running Linux for 9 years now. I prefer Linux over the BSD varients hands down. HOWEVER, there is no way I'm going to use Linux for a Firewall, and I'd even think twice before using it as a server. OpenBSD has now gone over three years without a remotely exploitable hole, when using the default install. The entire reason for OpenBSD's existance is security. My OS of choice for running a firewall would be OpenVMS, however, since the software to do firewall and NAT doesn't really exist for OpenVMS, I run OpenBSD. If you have enough machines around do a default install of what ever Linux distro you were thinking of on one, and OpenBSD on another. Then run some tools for checking for vulnerabilies against the two. You just might find the results disturbing. Zane
