SUA Server The SUA feature uses NAT to allow multiple workstations on your LAN to access the Internet while making the LAN appear as a single host. This provides the cost-saving benefit of an individual Internet account. However, some networks have internal server machines (web server, FTP server, etc.) that need to be made accessible to outside users. (This Setup Screen is available for ZyNOS 2.20 or above. RAS 1.5x and ZyNOS 2.1x don¡¦t have this feature included.) This screen allows you to configure eight internal servers for this purpose.

Description
Default Server and IP Address: The first entry in this screen is specified as Default. If you specify an IP address value for this field, then any service request that is not mapped to another port number will automatically go to this server. Port Number and IP Address: The internal server machines are specified using two parameters: port number and IP address. The port number refers to the specific service that the machine provides. RFC 1700 (Assigned Numbers) provides a comprehensive list of port numbers and their associated services. The IP address field refers to the address of the machine that provides the service. In this way, service requests from outside clients can be mapped to the correct machine.
