Local Start IP
This refers to the Inside Local Address (ILA), which is the starting local IP address. If
the rule is for all local IP addresses, then this field displays 0.0.0.0 as the
Local Start
IP
address. Local IP addresses are
N/A
for
Server
port mapping.
Local End IP
This is the end Inside Local Address (ILA). If the rule is for all local IP addresses, then
this field displays 255.255.255.255 as the
Local End IP
address. This field is
N/A
for
One-to-One
and
Server
mapping types.
Global Start IP This refers to the Inside Global IP Address (IGA), that is the starting global IP
address. 0.0.0.0 is for a dynamic IP address from your ISP with
Many-to-One
and
Server
mapping types.
Global End IP
This is the ending Inside Global Address (IGA). This field is
N/A
for
One-to-One
,
Many-to-One
and
Server
mapping types.
Type
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 (i.e., PAT, port address translation), ZyXEL's Single User
Account feature that previous ZyXEL routers supported only.
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
allows you to specify inside servers of different services behind the NAT to
be accessible to the outside world.
Modify

Click the delete icon to delete an existing address mapping rule. A window display
asking you to confirm that you want to delete the address mapping rule. Note that
subsequent address mapping rules move up by one when you take this action.
Insert
Click

to insert a new mapping rule before an existing one.
