I tried blocking on the WAN interface, then used IGMP as protocol, and
as destination 126.96.36.199
For source, I took "any", as the broadcast comes from various IP's
(sometimes my ISP gateway, sometimes a private IP ?)
I also left the private IP on blocked for my WAN (the one that is
possible to enable in Interfaces:WAN)
I've put the rule in front of all other rules, and made sure the logging
is not enabled... though the logging still fills with these requests...
It's not really an issue, it's just a bit messy, and the idea about
blocking it via a rule was a great idea, but it won't do it. (or I did
it wrong - very possible)
ps. This is the second time I try Monowall in a live situation, but so
far it really looks cool... great and quite easy interface... I intend
to buy an Alix board, so I can have a really fanless solution...
