Re: [FW-1] multicast on Checkpoint FW-1



Christopher,

 You'll need to run some kind of multicast routing daemon on your firewall
and make sure that the multicast traffic does not have any IP options set.
Checkpoint will drop any traffic where IP options are set (this directly
from the Israel R&D folks) out of hand (it's built into the kernel at
install time).  Otherwise, if you can route the multicast traffic you should
just have to turn on a rule to allow igmp (according to Checkpoint).
