Table 64 Address Mapping: Add/Edit
LABEL DESCRIPTION
Rule Name Type up to 20 alphanumberic characters for the name of this rule.
Type 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 VMG'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.
Local Start IP
Enter the starting Inside Local IP Address (ILA).
Local End IP 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.
Global Start IP 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.
