I was just reading a page describing bootps and bootpc, but I hadn't
realized yet that those were probably from other stations on the network. 
That makes sense.

So this isn't indicative of a problem in my configuration, other than the
fact that I am needlessly logging these?  How would I write an iptables
rule to drop these without logging them?

Something like:
iptables -A INPUT  -i eth0 -p udp --sport 67 --dport 68 -j DROP ?

Thanks,
Chris
