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.
