NAT Configuration Example
In this NAT example:
NAT is used for one-to-one mapping of addresses.
The Ethernet interface is in the private address space and the network
interface is in public address space. With NAT enabled, a single global PVC is
used to access the public network.
When using NAT, the network interface must be numbered because the
Ethernet interface is configured within the private address space.
The next hop router (default gateway) for the clients is the Ethernet IP address
of the router, 10.1.3.1.
There are four private IP addresses configured on the Ethernet side of the
router with NAT static mappings to four public IP addresses.
