The Goldfish Chronicles

Being your own admin is a great way to learn. Today I slowly pieced together how to set up an OpenBSD firewall, during going to the movies to watch Shrek 2 (poor), marking homework and reading JSF in Action appendices.

The one annoyance is that the 60 dollar server I’m going to use as a firewall has only got one on-board NIC, so with the addition of a network card via the riser, I am stuck at 2 and not the desired 3.

Biggest lesson. Firewall needs to be implementing every ip address I want to map through to the network beyond. It’s obvious, but just not something I considered as I sat learning how to NAT and block.

Now I just hope the machine proves stable, and that I can find some kind of monitoring tool for the tcpdumps.
