Firewalls (February 1995) |
While I most definitely agree with the idea of "buying" your UNIX from BSDI, if, for some reason, that's not an interesting option, I would like to point out that FreeBSD 2.0 and newer has packet-filtering firewall support code built right into the system (configurable as a kernel option). I personally believe in a mixture of packet filtering and application relays, and I find this combination quite useful if one doesn't have another device (ahem) that can act as a packet filter.
