10.8 The Address Mapping Screen

Ordering your rules is important because the Device applies the rules in the order that you specify.
When a rule matches the current packet, the Device takes the corresponding action and the
remaining rules are ignored.

DESCRIPTION
Choose the IP/port mapping type from one of the following.
One-to-One: This 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.
Many-to-One: This mode maps multiple local IP addresses to one global IP address. This is
equivalent to SUA (i.e., PAT, port address translation), the Device's Single User Account
feature that previous routers supported only.
Many-to-Many: This mode maps multiple local IP addresses to shared global IP addresses.
Enter the starting Inside Local IP Address (ILA).
Enter the ending Inside Local IP Address (ILA). If the rule is for all local IP addresses, then
this field displays 0.0.0.0 as the Local Start IP address and 255.255.255.255 as the Local
End IP address. This field is blank for One-to-One mapping types.
Enter 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 the Many-to-One mapping type.
Enter the ending Inside Global IP Address (IGA). This field is blank for One-to-One and
Many-to-One mapping types.
Select the number of the mapping set for which you want to configure.
Click OK to save your changes.
Click Cancel to exit this screen without saving.
