Hi Billy<br>
<br>
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.<br>
<br>
There is no special dhcpd.conf configuration required. A subnet declaration is
the same whether it is a locally attached or remote network.<br>
<br>
regards,<br>

from pool 192.168.1.x if the relay agent IP is 192.168.1.254. <br>
