4.1.2 DHCP Settings

DHCP allows individual clients to automatically obtain TCP/IP configurations when a server

starts up.

You can configure the CPE as a DHCP server or disable it when the CPE is working in

routing mode.

When configured as a DHCP server, the CPE automatically provides TCP/IP configuration for

the LAN clients that support DHCP client capabilities. If DHCP server services are disabled,

you must have another DHCP server on your LAN, or each client must be manually

configured.

4.2 Static Routing

If cascaded routers are used on the LAN, add static routing rules to ensure that the devices

connected to the cascaded routers can be accessed. Static routing is similar to dynamic routing.

However, manual configuration is required and the router must always be available.

±

If the IP address of the cascaded router is fixed, static routing is recommended.

±

If the IP address of the cascaded router is changeable, dynamic routing is recommended.

To configure static routing settings:

1.

Choose

LAN

>

Static

Routing

.

The

Static Routing

page is displayed.

2.

Click

Add

in the upper right corner of the

Static Routing

page.

3.

Set

Destination IP address

.

4.

Set

Subnet mask

.

5.

Set

Router IP address

. This IP address is obtained from the CPE and used for data

transmission to the cascading devices. This IP address must be reachable.

6.

Click

Submit

.

----End

4.3 Dynamic Routing

This function is enabled when cascaded routers are used on the LAN and the cascaded routers

comply with the Routing Information Protocol (RIP). This page allows you to enable or

disable RIP and set its version and operation mode.
