Configuring NAT

You can configure the following:
Many-to-one NAT—allows multiple devices on the internal network to
share one public IP address as they access the Internet. Many-to-one NAT
is based on the source address.
One-to-one NAT—allows Internet users to access a device on the internal
network. A public IP address is advertised on the Internet, but the device
on the internal network is actually using a private IP address. When the
ProCurve Secure Router receives a packet addressed to the advertised
public IP address, it translates this address to the actual private IP address
that the device is using. One-to-one NAT is based on the destination IP
address.

Configuring Many-to-One NAT

19. To configure many-to-one NAT, use the pull-down menu to select Many:1
NAPT for the Policy Type in the Add New Policy window. Click Continue.
