I apologise for a big mistake. I sent another post yesterday and I do not
know if it reached. You also will have to set the interfaces in
promiscuous mode and it's very important.

ifconfig eth1 promisc
ifconfig eth0 promisc

Another important thing, though you will have to enable bridging in the
kernel and recompile the kernel.

Yes, it's that simple. I have tested with two cards. But you can setup
as many segments as you can if your PC can accommodate (4 segments is what
I have heard of).

Routing and bridging together ? Alan should answer this because I could
not get the sl0 interface working after enabling bridging. If I disable
bridging sl0 starts working. It's reproducible. Also, firewalling does
not seem to work at the moment.
