Chapter 25 Network Address Translation (NAT)

This chapter discusses how to configure NAT on the HomeSafe.

25.1 Using NAT

)You must create a firewall rule in addition to setting up SUA/NAT, to allow traffic from the WAN to be forwarded through the HomeSafe.

25.1.1SUA (Single User Account) Versus NAT

SUA (Single User Account) is a ZyNOS implementation of a subset of NAT that supports two types of mapping, Many-to-Oneand Server. See section 25.3.1 for a detailed description of the NAT set for SUA. The HomeSafe also supports Full Feature NAT to map multiple global IP addresses to multiple private LAN IP addresses of clients or servers using mapping types.

)Choose Full Feature if you have multiple public WAN IP addresses for your HomeSafe.
