I think the problem here is that you have the adsl routers routing.
Personally, I think you'd find it easier to do what you want if you make
them do nothing but bridge, and handle the gateway stuff yourself in fbsd,
using natd and ipfw.

You'd need another couple of NICs though, and possibly a switch or two.

I'm probably wrong, though. But it's certainly where I'd start looking for
a solution.

Good luck.
