•
One to One
: In One-to-One mode, the ZyXEL Device maps one local IP address to one global IP
address.
•
Many to One
: In Many-to-One mode, the ZyXEL Device maps multiple local IP addresses to one
global IP address. This is equivalent to SUA (for instance, PAT, port address translation), ZyXEL’s
Single User Account feature that previous ZyXEL routers supported (the
SUA Only
option in
today’s routers).
•
Many to Many Overload
: In Many-to-Many Overload mode, the ZyXEL Device maps the
multiple local IP addresses to shared global IP addresses.
•
Many-to-Many No Overload
: In Many-to-Many No Overload mode, the ZyXEL Device maps
each local IP address to a unique global IP address.
•
Server
: This type allows you to specify inside servers of different services behind the NAT to be
accessible to the outside world.
Port numbers do NOT change for
One-to-One
and
Many-to-Many No Overload
NAT mapping
types.
