| You may want to research the bond device; but note: to do it right you have to have special hardware on the other side of your connection, which can be pricey. |

Yes, this is relatively easy, and you don't need to use bridging (which is a much more clumsy approach). Turn Proxy-ARP on both interfaces, and modify the routing table so that one side knows about the /29 network and the other side only knows a specific route to the next-hop gateway. Configure all the client machines with the address of the gateway (not your router). Voila. There are more thorough howto's on-line...

Or just Google for "Proxy-ARP Linux" and you will find plenty of examples.
