/var/log/messages full of network crap, how to stop?

Hi there. So I got a cable modem recently and since then my /var/log/messages has looked like this:

And it is chock full of that. It sort of renders the log useless. I hate to admit I don't know where this is coming from. I'm using guarddog for a firewall. I'm on kernel 2.4.26. Obviously the log dosn't say "my.ip.address" and "my.ip.net.255", it actually has the ips in there.
Any ideas, or maybe a shove in the right direction. It may just be I am searching for the wrong terms and there is an easy answer I've missed.

Search your guarddog script (presumably in /etc/init.d) for lines containing "-j LOG" and try commenting these out. Most of the stuff you posted seems to come from iptables.
