Network Address Translation (NAT) translates private addresses into public addresses. It
conserves IPv4 addresses and improves network security by shielding the private network
topology.

NAT enables hosts on a private network to access the public network.
3.2 NAT Features Supported by the SPU
The SPU supports the following NAT features: static NAT, port address translation (PAT),
internal server, NAT Application Level Gateway (ALG), NAT filtering, NAT mapping, Easy
IP, twice NAT, and NAT multi-instance.
3.3 Configuring NAT
To implement communication between the private network and the public network through
NAT, use Easy IP for a single user and an address pool for multiple users.
