DESCRIPTION

 

 

Type

Choose the port mapping type from one of the following.

 

• One-to-One: One-to-One mode maps one local IP address to one global IP

 

address. Note that port numbers do not change for One-to-one NAT mapping

 

type.

 

• Many-to-One: Many-to-One mode maps multiple local IP addresses to one

 

global IP address. This is equivalent to SUA (i.e., PAT, port address translation),

 

ZyXEL's Single User Account feature that previous ZyXEL routers supported

 

only.

 

• Many-to-Many Overload: Many-to-Many Overload mode maps multiple local IP

 

addresses to shared global IP addresses.

 

• Many-to-Many No Overload: Many-to-Many No Overload mode maps each

 

local IP address to unique global IP addresses.

 

• Server: This type allows you to specify inside servers of different services behind

 

the NAT to be accessible to the outside world.

Local Start IP

This is the starting local IP address (ILA). Local IP addresses are N/A for Server port

 

mapping.

Local End IP

This is the end local IP address (ILA). If your rule is for all local IP addresses, then

 

enter 0.0.0.0 as the Local Start IP address and 255.255.255.255 as the Local End

 

IP address.

 

This field is N/A for One-to-Oneand Server mapping types.

 

 

Global Start IP

This is the starting global IP address (IGA). Enter 0.0.0.0 here if you have a dynamic

 

IP address from your ISP.

Global End IP

This is the ending global IP address (IGA). This field is N/A for One-to-One, Many-

 

to-Oneand Server mapping types.
