[GRLUG] AT&T Uverse TV + 6to4 = ?

[Michael Mol]

I haven't done anything specific with IGMP routing, but my
recommendation would be to switch away from using something like
OpenWRT and use a low-end x86 PC with a couple cheap NICs in it. I'd
bet you could throw together a sufficient machine out of spare parts,
possibly with the aid of a couple $5-$15 NICs you can get from any of
the local non-chain computer stores.

Then load Linux on the box and go to town with firewall distros, or
roll your own while learning the protocols in question.
