I am trying to get multicast traffic to traverse 3 different subnets call connected to the same linux router. This is primarily to get rendezvous/zeroconf services working for Macs on the network. Being able to experiment with the VideoLAN client''s multicasting abilities would be a bonus. I see that rendezvous sends out packets with a TTL of 1 and expects them back with a TTL of 255 so I guess I will have to do some packet mangling in iptables. The limited documentation out there recommends running a multicast router like PimD. What does this add to the setup? Surely it''s just a cast of some iptables rules allowing 224/4 between networks? Am I missing the point here? Any good documents on multicast? S. -- Simon Tennant ________________ http://imaginator.com/~simon/contact
