Filtering out igmp packets

["Stan Brown" <stanb_(_at_)_awod_(_dot_)_com>]

I am seting up an OpenBSD 2.7 x86 machine to be my gateway/firewall/nat machine. I
seem to have a noisy neighbor :-(

I am connected via an @hom cablemode. I have everything basicly working (Thanks to
all the helpful listmembers who helped me with this!) However I really can't work
on the machine because every 15 seconds or so ipmon blasts a message about my
neighbors igmp packets :-(

It was sugested that I cahnge the rule which is being trigered for this to not log.
Unfortunatley I can't figure out how to write a rule specific to this packet type.

Sugestions?
