It seems that a lot of people are interested in IGMP proxying in order to watch multicast IPTV streams from their ISP.

In my case, I am using the router to run two subnets, one for actual stuff, another for non-trusted people to use the Internet.

I would like to be able to do Ghost imaging (Ghost is running in the primary subnet) of the machines in the non-trusted subnet, but it seems that the multicast traffic isn't going through properly. I CAN do this within the primary subnet.

I got igmpproxy running and can see the route announcements in the log, but I assume I have it mis-configured. Maybe I will go back to pimd and play with that.

I guess if all else fails, I can always switch the VLAN of the port that serves that segment when I want to do imagine and switch it back later :) ... I just thought this might be a good opportunity to try and see if I can get multicast to run properly.

Thanks,
Bill

P.S. This router is still running Sugarland...should that be an issue?

pimd is included by default.

But does pimd really do IGMP-proxying?
No, it does real IGMP. :)

There may be some firewall issues with it.

I can't find any mention of IGMP
proxying in the pimd manual I found. ISPs generally do not allow residential
customers to talk PIM with the network, they expect an IGMP join, which is
what an IGMP proxy would do.
Sample application?
