[streaming] Re: Multicast streaming over VPN

[Martin Forget]

we did the same thing and it works great.

cisco 3750 layer 3 at the core (for GRE tunnel termination)

linksys WRT54G with openwrt at the cpe


the linksys initiates a gre tunnel to the cisco switch/router,

you also need an igmpproxy daemon running on openwrt to forward the  
igmp messages over the tunnel
and some static routing in openwrt.

the network architecture looks like:
settobox/vlc client-->lan(private) -->igmp_proxy-->gre tunnel-->NAT 
(linksys)-->internet-->gre terminator-->multicast network


i dont' remember the exact igmpproxy software that we had to cross- 
compile for linksys MIPS processors
but if you want, i could find out... or get a binary
