9.1 NAT Overview - Continued
9.1.5 NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
> One to One:
In One-to-One mode, the 1500WR Wireless Router maps one local IP address to one
global IP address.
> Many to One:
In Many-to-One mode, the 1500WR Wireless Router maps multiple local IP address-
es to one global IP address. This is equivalent to SUA (i.e., PAT, port address translation), ParkerVi-
sion’s Single User Account feature (the SUA Only option).
> Many to Many Overload:
In Many-to-Many Overload mode, the 1500WR Wireless Router maps the
multiple local IP addresses to shared global IP addresses.
> Many One to One:
In Many-One-to-One mode, the 1500WR Wireless Router 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-One-to-One NAT mapping types.
The following table summarizes these types.
