If you're running 3.0 or later, try ipfw(8) and look for the 'forward=B4 action. A rule like # ipfw add ip from 206.x.x.y to any forward 206.x.x.1 should forward all packets originating in 206.x.x.y to the gateway on the 206.x.x.y network. If you have locally attached machines, or more than = one gateway, I would guess it doesn't work.
