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
