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.
