Indeed. The only reason I put a block rule in for it here is to get rid
of the log entries, and the only reason it's a block rule is because
m0n0wall doesn't support multicasting.

I have a no-log rule for IGMP here, as well as logging enabled for the
default rule, and it works fine. You must either have the rule wrong, or
have an earlier rule that matches the packets.
