The design goal of ZyXEL's SUA is to minimize the Internet access cost in a small office environment by using
a single IP address to represent the multiple hosts inside. It does more than IP address translation, so that
multiple hosts on the LAN can access the Internet at the same time.
How many network users can the SUA/NAT support?
The ZyXEL Device does not limit the number of the users but the number of the sessions. The ZyXEL Device
supports 1024 sessions that you can use the 'ip nat iface enif0 disp' command in menu 24.8 to view the current
active sessions.
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'.
Why can't I configure device filters or protocol filters?
In ZyNOS, you can not mix different filter groups in the same filter set.
