[Cialug] DHCP Relay

[Nathan C. Smith]

Take Two.

in other words, the DHCP server itself is smart enough not to lease the
addresses on the remote subnet to the local subnet?

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.
