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.


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