SUA (Single User Account) is a implementation of a subset of NAT that supports two types of 

mapping, Many-to-One and Server. The BIPAC-5100/5100W also supports Full Feature NAT 

to map multiple global IP addresses to multiple private LAN IP addresses of clients or servers 

using mapping types as outlined in 

A SUA server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, 

that you can make visible to the outside world even though SUA makes your whole inside 

network appear as a single computer to the outside world. 

You may enter a single port number or a range of port numbers to be forwarded, and the local 

IP address of the desired server. The port number identifies a service; for example, web 

service is on port 80 and FTP on port 21. In some cases, such as for unknown services or 

where one server can support more than one service (for example both FTP and web service), 

it might be better to specify a range of port numbers. You can allocate a server IP address that 

corresponds to a port or a range of ports. 

Many residential broadband ISP accounts do not allow you to run any server processes (such 

as a Web or FTP server) from your location. Your ISP may periodically check for servers and 

may suspend your account if it discovers any active services at your location. If you are unsure, 

refer to your ISP. 

Default Server IP Address 

In addition to the servers for specified services, NAT supports a default server IP address. A 

default server receives packets from ports that are not specified in this screen.
