Configuring NAT Rules to Securely Access a Remote Network

NOTE: One-to-one translation will be performed for port range forwarding. For example, if you want to translate an original TCP service with the port range of 50000 to 50002 to a TCP service with the port range of 60000 to 60002, then the port 50000 will be translated to the port 60000, the port 50001 will be translated to the port 60001, and the port 50002 will be translated to the port 60002.

•Translated IP: Choose the IP address of your local server that needs to be translated. If the IP address that you want is not in the list, choose Create a new address to create a new IP address object. To maintain the IP address objects, go to the Networking > Address Management page. See Address Management, page175.

•WAN: Choose either WAN1 or WAN2, or both as the incoming WAN port.

•WAN IP: Specify the public IP address of the server. You can use the IP address of the selected WAN port or a public IP address that is provided by your ISP. When you choose Both as the incoming WAN port, this option is grayed out.

•Enable Port Forwarding: Click On to enable the port forwarding rule, or click Off to create only the port forwarding rule.

•Create Firewall Rule: Check this box to automatically create a firewall rule to allow access so that the port forwarding rule can function properly. You must manually create a firewall rule if you uncheck this box.

NOTE: If you choose Both as the incoming WAN port, a firewall rule from Any zone to Any zone will be created accordingly.

•Description: Enter the name for the port forwarding rule.
