When you configure group members for 1to1, unique addresses are assigned for each session from a pool of
Every subscriber uses a unique
•1to1 reverts to normal NAT (port mapped).
•1to1 unique does not allow a new session.

To configure the IP type for members of the active/current group, use the following command:
iptype {default NAT static DHCP 1to1 1to1Unique}
