Setting Up One-to-One NAT

Use the Setup > One-to-One NAT page to enable One-to-One NAT (Network Address Translation). This process creates a relationship that maps a valid external IP address to an internal IP address that is hidden by NAT. Traffic can then be routed from the Internet to the specified internal resource.

NOTE For best results, reserve IP addresses for the internal resources that you want to reach through one-to-one NAT. See About Static IP Addresses (for IPv4 Only), page 66.

You can map a single relationship, or map an internal IP address range to an external range of equal length (for example, three internal addresses and three external addresses). The first internal address is mapped to the first external address, the second IP internal IP address is mapped to the second external address, and so on.

To open this page: Click Setup > One-to-One NAT in the navigation pane.
