AT-AR256E v3 4 Ports ADSL2/2+ Router User Manual

A database of predefined port forwarding rules allows you to apply one or more rules to one or more

members of a defined LAN group. You can view the rules associated with a predefined category and add the

available rules for a given category. You can also create, edit or delete your own port forwarding rules.

To configure port forwarding:

Select Advanced.

Select Application > Port Forwarding.

Select WAN Connection, LAN Group and LAN IP. If the desired LAN IP is not available in the

LAN IP drop-down menu, you can add it using the LAN Client page, which is accessed by clicking

New IP.

Select the available rules for a given category and click Add to apply the rule for this category. If a rule

is not in the list, you can create your own rule in the User category. Select User, and then click New.

The Rule Management page opens for you to create new rules. Enter Rule Name, Protocol, Port

Start, Port End and Port Map then click Apply.

Continue to add rules as they apply from each category.

Click Apply to temporarily activate the settings.

To make changes permanent, click Save Settings.

DMZ Settings

Setting a host on your local network as demilitarized zone (DMZ) forwards any network traffic that is not

redirected to another host via the Port Forwarding feature to the IP address of the host. This opens the

access to the DMZ host from the Internet. This function is disabled by default. By enabling DMZ, you add an

extra layer of security protection for hosts behind the firewall.

To enable DMZ Settings:

On the Port Forwarding page, select Enable DMZ. This opens the DMZ Settings page.

Select the WAN Connection, LAN Group and LAN IP Address.

Click Apply to temporarily apply the settings.

To make changes permanent, click Save Settings.

Custom Port Forwarding

The Custom Port Forwarding page allows you to create up to 15 custom Port Forwarding entries to

support specific services or applications, such as concurrent NAT/NAPT operation.
