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.
