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



Hello Christophe,

I've been trying to set up multicast rounting in 4.1/SP3 running on Linux
Redhat 7.0 and by using mrouted... and it didn't work. If firewall's not
running, then routing works. When FW module is up, rule 0 anti-spoofing
stops multicast packets by default. I've set antispoofing off in interface
level, but it doesn't work. Among checkpoint local support, they say rule 0
is enforced in kernel level and cannot be altered by configuring rules.

I did some minor kernel hacking but it still wouldn't work.

Officially multicast routing is not supported by checkpoint.

The basic problem why this is not supported by Checkpoint is that it's a
major security issue becayse multicast address are not individual machine
addresses, rather services...


If you really get this working with mrouted, please let me know.
