Prestige 1100 Internet Access Router

3-8 Internet Access

3.6 Single User Account

Typically, if there are multiple users on the LAN wanting to concurrently access the Internet, you will have

to lease a block of legal, or globally unique, IP addresses from the ISP.

The Single User Account (SUA) feature allows you to have the same benefits as having multiple legal

addresses, but only pay for one IP address, thus saving significantly on the subscription fees. (Check with

your ISP before you enable this feature).

The Single User Account feature may also be used on connections to remote networks other than the ISP.

For example, this feature can be used to simplify the allocation of IP addresses when connecting branch

offices to the corporate network.

The IP address for the SUA can be either fixed or dynamically assigned. In addition, you can designate

servers, e.g., a web server, on your local network and make them accessible to outside world.
