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.
