Chapter 9 Network Address Translation (NAT)
DESCRIPTION
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.
