Since the assigned name is mapped to an IP address, the device's IP address should not change. To ensure that the device keeps the same IP
address, go to Network Settings > DHCP Server and reserve the IP address for the device by selecting the device in the Active Leases list and
clicking "Reserve".
Firewall
The router automatically provides a firewall. Unless you configure the router to the contrary, the router does not respond to unsolicited incoming
requests on any port, thereby making your LAN invisible to cyber attackers.
However, some network applications cannot run with a tight firewall. Those applications need to selectively open ports in the firewall to function
correctly. The options on this page control ways of opening the firewall to address the needs of specific types of applications.
Select from the following tabs to edit your firewall configuration:
• Port Forwarding Rules
• Network Prefix Translation
• DMZ (DeMilitarized Zone)
• Remote Admin. Access
• Application Gateways
• Firewall Options
• Zone Firewall
Port Forwarding Rules
A port forwarding rule allows traffic from the Internet to reach a computer on the inside of your network. For example, a port forwarding rule might
be used to run a Web server.
NOTE: Exercise caution when adding new rules as they impact the security of your network.
Click Add to create a new port forwarding rule, or select an existing rule and click Edit.
Add/Edit Port Forwarding Rule
• Name: Name your rule.
• Enabled: Toggle whether your rule is enabled. Selected by default.
• Use Port Range: Changes the selection options to allow you to input a range of ports (if desired).
• Internet Port(s): The port number(s) as you want it defined on the Internet. Typically these will be the same as the local port numbers, but
they do not have to be. These numbers will be mapped to the local port numbers.
• Local Computer: Select the IP address of an attached device from the dropdown menu, or manually input the IP address of a device.
