4.6 Route

This topic describes how to configure the default route and static route through the Web page.

4.6.1 Default Route Configuration

1.

In the navigation tree on the left, choose

Route

>

Default Route Configuration

. In the

pane on the right, select or deselect the

Default Route

option button to enable or disable

the default route of the system, as shown in

Figure 4-22

.

Default Route Configuration

NOTE

If an ONT fails to find a matching routing entry after receiving a packet, the WAN interface specified

by the default route configuration sends the packet to a network device. Before the default route of

the system is enabled, the WAN interface must obtain the IP address. Therefore, the parameters of

the WAN interface must be correctly set. For details, see

4.2.1 WAN Configuration

to apply the configuration.

The demilitarized zone (DMZ) is a technology that enables the ONT to forward all received

packets through a specified internal server. The technology enables a computer in the LAN to

be completely exposed to all users on the Internet or enables the mutual communication without

restrictions between a host with a specified IP address and other users or other servers on the

Internet. In this way, many applications can run on the host with the specified IP address. The

host with the specified IP address receives all connections and files that can be identified.

CAUTION

If the LAN-side device does not provide website service or other network services, do not set

the device to a DMZ host because all ports of a DMZ host are opened to the Internet.

Table 4-9

describes the parameters related to the DMZ.

Table 4-9

Parameters related to the DMZ

Parameter

Description

Interface Name

Indicates the name of the WAN interface. If the WAN interface

is not in the port mapping table, the application requests from

the WAN connection are directly forwarded to the host in the

DMZ.

Host Address

Indicates the IP address of the DMZ host.

Enable DMZ

Indicates whether to enable the DMZ.

the Intranet host IP address and port ID to Extranet IP address and corresponding port ID so that

users from Extranets can access the Intranet server. With port mapping, the users cannot see the

Intranet IP address and they see the Extranet IP address.

Table 4-10

describes the parameters related to port mapping.
