How Many Network Users Can The Sua/Nat Support - ZyXEL Communications P-793H v2 Support Notes

Many to One: In Many-to-One mode, the P-793H 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 is optional in today's P-793H v2 routers).
Many to Many Overload: In Many-to-Many Overload mode, the
P-793H v2 maps multiple ILA to shared IGA.
Many One-to-One: In Many One-to-One mode, the P-793H v2 maps
each ILA to unique IGA.
Server: In Server mode, the P-793H 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 the five types.
NAT Type IP Mapping
One-to-One ILA1<--->IGA1

ILA2<--->IGA1
(SUA/PAT)

14. How many network users can the SUA/NAT support?

The P-793H v2 does not limit the number of the users but the number of the
NAT sessions. The P-793H v2 supports 2048 sessions that you can use the 'ip
nat session' command in CLI to see. You can also use „ip nat hashTable
wanif0‟ to view the current active NAT sessions. Or you can check it in below
WEB Configurator.
