To edit an address mapping rule, click the rule’s link in the NAT Address Mapping Rules
screen to display the screen shown next.
Type:
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), Billion's Single User
Account feature that previous Billion 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.

This is the starting Inside Local IP Address (ILA). Local IP
addresses are N/A
for Server
port mapping.

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.
