I happen to be a ccnp and mcse. I get how ip helper-address works. Also
work with microsoft dhcp servers.
How do you setup a scope for a remote subnet, and how does the dhcp server
know how to hand out the correct ip leases for a non-connected subnet?
Does the dhcp server look at the source address of the interface of the
forwarded helper-address packets? Then match up the correct scope with the
router interface ip address?
