How Many Network Users Can The Sua/Nat Support - ZyXEL Communications P-660R-T1 Support Notes

3. Many to Many Overload
In Many-to-Many Overload mode, the P-660 maps the multiple ILA to shared IGA.
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.
