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.
