We have been trying to set up the FW-1's protecting various subnets from our
production back bone network to support IP Multicast...the MS Media Saerver
and Vbrick units are on the production backbone and IP Multicast to all
subnets (without FW-1 firewalls) and subnet switches fine....However when
the IP multicast hits those subnets protected by the FW-1's...on the
protected side of the firewall...the protocol changes to unicast and
broadcast to all ports on the switch....we are using cisco switces and have
enabled multicast options and protocols on them...we know that the
work...the problem seems to be the FW-1 not enabling Multicast thru from the
production backbone to the FW-1 protected subnets can any one assist with a
solution...I am sure that we are not the only ones with this problem...Best
Regards...Phil
