Check Relay Agent IP address

[Glenn Satchell]

Hi Billy

The dhcp server does this automatically. If a request comes in from a 
remote subnet, the dhcp relay agent adds in the gateway address as it 
forwards the packet. The dhcp server looks at this gateway address and 
automatically matches it with a subnet declaration for you.

There is no special dhcpd.conf configuration required. A subnet 
declaration is the same whether it is a locally attached or remote network.
