Table 7-6 Address Mapping Edit
LABEL DESCRIPTION
Type Choose the port mapping type from one of the following.
1.
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.
2.
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.
3.
Many-to-Many Overload : Many-to-Many Overload mode maps multiple local IP
addresses to shared global IP addresses.
4.
Many One-to-One : Many One-to-one mode maps each local IP address to unique
global IP addresses.
5.
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 Inside Local IP Address (ILA). Local IP addresses are N/A for
Server port mapping.
Local End IP This is the end Inside 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-One and Server mapping types.
