Enable SUA
Network Address Translation (NAT) allows the translation of an Internet
protocol address used within one network to a different IP address known
within another network.
SUA (Single User Account) is a subset of NAT that supports two types of
mapping: Many-to-One and Server. When you select this option the device
will use Address Mapping Set 255 in the SMT (see the section on menu 15.1
for more information).
Select the check box to enable SUA. Clear the check box to disable SUA so
the device does not perform any NAT mapping for the dial backup
connection.

would like to read more detailed information about inter operability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
