SUA (Single User Account) versus NAT

SUA (Single User Account) is an implementation of a subset of NAT that supports
two types of mapping, Many-to-One and Server. The Business Secure Router
also supports Full Feature NAT to map multiple global IP addresses to multiple
private LAN IP addresses of clients or servers using mapping types. Select either
SUA Only or Full Feature in WAN IP.
NN47922-500
summarizes these types.
Note: You must create a firewall rule in addition to setting up SUA/
NAT, to allow traffic from the WAN to be forwarded through the
Business Secure Router.
