Freebsd + netgraph, multicast from home to work

I suddenly wanted to see the TV multicaste at work. Purely of sporting interest.
Two servers were taken with Freebsd and 30 minutes to configure. Look 2x2 :)

I remembered an article about ethernet over the Internet written a couple of years ago.

Nergraph modules are required - ng_bridge, ng_iface, ng_socket. Rebuilding the kernel, and building igmpproxy from ports.

If anyone is interested in how to collect all this, sign off, I will prepare a general article.
