There are a couple ways. If you have a cisco at the far end, you put 
something like
ip helper-address x.x.x.x
in the interface config of the interface that will be receiving the 
bootp requests.

Set up a new subnet on your dhcp server containing the network on the 
far ethernet interface and you are all set.
