how to extend exsisting lan to remote site.

We have bought two 1600 routers with serial interfaces and are going to connect two locations over a leased line using ppp on the leased line. Is it possible to configure the routers to be on the same ip subnet. The normal configuration shows that they must be on different subnets effectivly linking two seperate networks. We would like to be able to just extend our existing network to the remote site if this is possible.

Re: how to extend exsisting lan to remote site.

This can be achieved through implementing bridging as opposed to routing over the link. You basically need to setup a bridge-group and add this bridge-group to your LAN and WAN interfaces on both sides of the link. In this way you can have one large subnet spanning a WAN link and no need to renumber. Something to keep in mind is that traffic across the WAN link may be considerable as certain traffic for the local LAN may actually also traverse the WAN.
