About This Chapter
Network Address Translation (NAT) can translate private and public addresses. The shortage
of IPv4 address can be solved and the topology of the private network can be shielded. The
network security is thus improved.
3.1 NAT Overview
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, you can use Easy IP for a single user and the address pool for multiple users.
3.4 Configuration Examples
