More network upgrades

In addition to all getting the topology set up more sanely, I’ve moved the network allocation functions off onto the WRT54GL. Now computers connected to my wireless can continue to access the Internet even if ylum is down or off-line.

Practically speaking, I put the DHCP server and a lightweight DNS server up on the little router. These are actually part of the same program, dnsmasq, that comes with OpenWRT. The result is that even if ylum is sick for days, or I’m fooling with it, laptops and other local machines can still reach the rest of the world. Hmmmm. Might be a good time to invest in some MXes, though…

In any case all of this should be invisible to the outside world, but makes me a little happier.
