LABEL DESCRIPTION
Rule Name Type up to 20 alphanumeric characters for the name of this rule.
Type Choose the IP or 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 (for example, 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.
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.
Global End IP Enter the ending Inside Global IP Address (IGA). This field is blank for One-to-One
and Many-to-One mapping types.
WAN Interface Select a WAN interface to which the address mapping rule applies.
