Problems with mtrace through a PIX firewall

I have been able to get multicast to work throught the my PIX 515E running 7.12. That was not a problem. What I can't seem to get to work is mtrace through this firewall. Can this be done?

I have tried different combinations of rules allowing responses to the 224.0.1.32(mtrace response) but to no avail. What am I missing? Any help would be appreciated.

Very Respectfully,

Raul F. Fernandez

Re: Problems with mtrace through a PIX firewall

Enable the following debugs

debug ip pim

debug ip mrouting x.x.x.x detail

debug ip igmp

The IGMP debug will give an idea why the PING us not happening.
