One-to-One NAT

One-to-One NAT maps valid, external addresses to private addresses hidden by NAT.
Computers on your private LAN are accessed on the Internet at the corresponding public IP
addresses.
Note: The functionality of this feature can be affected if a WAN Failover to the modem occurs
on the SP.
You can create a relationship between internal and external addresses by defining internal and
external address ranges of equal length. Once the relationship is defined, the computer with the
first IP address of the private address range is accessible at the first IP address of the external
address range, the second computer at the second external IP address, etc.
To configure One-to-One NAT, complete the following instructions.
1. Select the Enable One-to-One NAT check box.
2. Enter the beginning IP address of the private address range being mapped in the Private
Range Begin field. This is the IP address of the first machine that is accessible from the
Internet.
3. Enter the beginning IP address of the valid address range being mapped in the Public
Range Begin field. This address should be assigned by your ISP.
Note: Do not include the SonicWALL WAN IP (NAT Public) Address or the WAN
Gateway (Router) Address in this range.
