2)
DHCP Relay:
In this mode, the Router will work as a DHCP Relay. A DHCP relay is a device
that forwards DHCP data between computers that request IP addresses and the DHCP server
that assigns the addresses. Each of the device's interfaces can be configured as a DHCP relay.
In this mode, the DHCP requests from local PCs will be forwarded to the DHCP server running
on WAN side.
Figure 4-10
Relay Server:
Enter the IP Address of the DHCP server running on WAN side.
3)
DHCP Server:
Select this mode, then the screen will be shown as in Figure 4-11. The Router
will work as a DHCP Server; it becomes the default gateway for DHCP client connected to it.
That device on your local network must be set as a DHCP client to obtain the IP address
automatically. By default, the DHCP Server is enabled.
