ZyXEL Communications P-660 series User Manual

P-660 Series Support Notes
4. Many One-to-One
In Many One-to-One mode, the P-660 maps each ILA to unique IGA.
5. Server
In Server mode, the P-660 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 IP Mapping

16. How many network users can the SUA/NAT support?
The Prestige does not limit the number of the users but the number of the sessions.
The P-660 supports 1024 sessions that you can use the
'ip nat iface wanif0 st'
command in menu 24.8 to view the current active sessions.
17. What are Device filters and Protocol filters?
In ZyNOS, the filters have been separated into two groups. One group is called
'device filter group', and the other is called 'protocol filter group'. Generic filters
belong to the 'device filter group', TCP/IP and IPX filters belong to the 'protocol filter
group'.
