4.6.3.1 DMZ configuration

Setting a computer (on your local network) as a DMZ forwards any network traffic that is not redirected to another computer via the port-forwarding feature to the computer's IP address. This opens the access to the DMZ computer from the Internet.

4.6.3.2 Enable Web from WAN

Enabling the Web from WAN on your local network allows Web requests that come from the Internet to be re-routed to a Web Server that is on a different subnet. This is different that the Web server rule that is configurable via the port-forwarding page. In this case, the web server is on a different subnet.

4.6.3.3 Enable Remote Telnet

Enabling the Remote Web on your local network allows telnet requests that come from the Internet to be re-routed to a telnet Server that is on a different LAN IP subnet. This is different that the telnet server rule that is configurable via the port-forwarding page. In this case, the telnet server is on a different subnet.

4.6.3.4 Enable Incoming ICMP Ping

Enabling the Incoming Internet Control Message Protocol (ICMP) Ping will allow Echo requests to come into the gateway. The gateway will respond with an ICMP Echo response message. The option allows the DSL provider or ISP to determine the following:

a.The status of the network.

b.Tracking and isolating hardware and software problems.

c.Testing, measuring, and managing networks.

4.6.4 Access Control

Access control can also be called port blocking. Specific types of traffic that is destined to a selected LAN IP address can be blocked. To enable any of the Access Control features, click Advanced and under Advanced, select Access Control. A page similar to the port-forwarding page appears. Similar to the port-forwarding page, an IP address can be added to a rule. All Access Control rules have precedence over rules that were added via the port-forwarding page.

4.6.5 LAN clients

To add a LAN client, click Advanced and under Advanced, select LAN Clients. If DHCP is used, all DHCP clients are automatically assigned. If a fixed IP address server is on the LAN and you want this server to be visible via the WAN, you must add its IP address. Once the IP address has been added to you can apply Port Forwarding and Access Control rules to this IP address.

4.6.6 MAC Address Filters

The MAC filtering mechanism provides a way for the users to define rules to allow/deny frames
