I'm getting tons of those.

[root@crasher2 /root]# /sbin/ipfwadm -M -l
IP masquerading entries
prot expire source destination ports
tcp 14:59.84 moocow1.ttgcitn.com thing.dreamscape.com 1935 (61001) -> irc

It's happened ever since I started using IP masquearading, a few dozen
kernels ago. They are very annoying (6 out of 10 syslog'd messages consist
of that). Any ideas on how to get rid of them? ;-) Thanks. -rt
