DESCRIPTION
This is the rule index number.
This is the starting Inside Local IP Address (ILA). Local IP addresses are N/A for Server
port mapping.
This is the end Inside Local IP Address (ILA). If the rule is for all local IP addresses, then
this field displays 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.
This is the starting Inside Global IP Address (IGA). Enter 0.0.0.0 here if you have a
dynamic IP address from your ISP. You can only do this for Many-to-One and Server
mapping types.
This is the ending Inside Global IP Address (IGA). This field is N/A for One-to-one,
Many-to-One and Server mapping types.
1-1: 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.
M-1: 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.
M-M Ov (Overload): Many-to-Many Overload mode maps multiple local IP addresses to
shared global IP addresses.
MM No (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.
Click the edit icon to go to the screen where you can edit the address mapping rule.
Click the delete icon to delete an existing address mapping rule. Note that subsequent
address mapping rules move up by one when you take this action.
