P-660R-Tx v2 Series Support Notes
In One-to-One mode, the P-660R-Tx v2 maps one ILA to one IGA.
•
Many to One
In Many-to-One mode, the P-660R-Tx v2 maps multiple ILA to one IGA. This is
equivalent to SUA (i.e., PAT, port address translation), ZyXEL's Single User
Account feature that previous ZyNOS routers supported (the SUA only option
in today's routers).
•
Many to Many Overload
In Many-to-Many Overload mode, the P-660R-Tx v2 maps the multiple ILA to
shared IGA.
•
Many One-to-One
In Many One-to-One mode, the P-660R-Tx v2 maps each ILA to unique IGA.
•
Server
In Server mode, the P-660R-Tx v2 maps multiple inside servers to one global
IP address. This allows us to specify multiple servers of different types behind
the NAT for outside access. Note, if you want to map each server to one
unique IGA please use the One-to-One mode.
The following table summarizes these types.
NAT Type

13. How many network users can the SUA/NAT support?
The Prestige does not limit the number of the users but the number of the NAT
sessions. The P-660R-Tx v2 supports 1024 sessions that you can use the ‘ip
nat session’ in
CLI
to see. You can also use
'ip nat iface wanif0 st'
T
command
to view the current active sessions.
