4.2.5.3 Configuring Address Mapping

To change your BIPAC-5100/5100W’s address mapping settings, click NAT, Select Full

Feature and click Edit Details to open the following screen.

Local Start IP: This is the starting Inside Local IP Address. Local IP addresses are

N/A for Server port mapping.

Local End IP: This is the end Inside Local IP Address (ILA). If your rule is for all

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.

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. You can only do this for

Many-to-One and Server mapping types.

Global End IP: 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.

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.
