Address Mapping Edit
The following table describes the labels in this screen.
17.5 Port Forwarding
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or
FTP, that you can make visible to the outside world even though NAT makes your whole
inside network appear as a single computer to the outside world.

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

addresses, then enter 0.0.0.0 as the

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.
Global Start IP
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.
