Description
1. One-to-One mode maps one local IP address to one global IP
address. Note that port numbers do not change for the One-to-one NAT
mapping type.
2. Many-to-One mode maps multiple local IP addresses to one global
IP address. This is equivalent to SUA (that is, PAT, port address
translation), the Single User Account feature.
3. Many-to-Many Overload mode maps multiple local IP addresses to
shared global IP addresses.
4. Many One-to-One mode maps each local IP address to unique
global IP addresses.
5. Server permits you to specify inside servers of different services
behind the NAT to be accessible to the outside world.
