DMZ Host

DMZ allows all the ports of a PC on your LAN to be exposed to the Internet. Set the IP

address of the PC to be DMZ host, so that the DMZ host will not be blocked by

firewall.

Choose Advanced Setup > NAT > DMZ host to display the following page.

Figure 79 DMZ host

In this page, enter the IP address of the DMZ host.

After finishing the settings, click the Apply/Save button to apply the settings.

If you want to clear the DMZ function of the host, please delete the IP address of the

host in the field of DMZ Host IP Address, and then click the Apply/Save button.

5.2.5 Security

By default, the firewall is enabled. The firewall is used to block the file transmission

between the Internet and your PC. It serves as a safety guard and permits only the

authorized files to be sent to the LAN.

Note:

If the DSL router is configured to be bridge mode, IP filtering is disabled and the IP

filtering interface does not appear.

Outgoing IP Filtering Setup

When the outgoing IP filtering settings is enabled on the DSL router, the security

functions for the local network are enabled at the same time.

Choose Security > IP Filtering > Outgoing and the following page appears.
