Static Nat seems not working with multicast

[minhhaivietnam]

Hi all,

I have a topology running multicast:

router1(multicast receiver)----checkpoint r80----router2(RP)---router3(multicast sender)

all devices run pim-sm.

above network run fine without nat.

but when i set static nat on firewall: IP of router1---> translate to a.b.c.d

then on router1, I send "igmp join" toward to RP(router2). On log , i see that igmp packet is forwarded to firewall, but packet is not nated to a.b.c.d (above ip address). And not forwarded through firewall.

So my question is if checkpoint r80 supports multicast nat source? If yes , how i can config it?

Thank you!!

We do not support NAT with PIM.
