LABEL DESCRIPTION
Add New Rule Click this to create a new rule.
Rule Name This is the name of the rule.
Local Start IP This is the starting Inside Local IP Address (ILA).
Local End IP This is 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 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 the Many-to-One 
mapping type.
Global End IP This is the ending Inside Global IP Address (IGA). This field is blank for One-to-One 
and Many-to-One mapping types.
Type This is the address mapping type.
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.
WAN Interface This is the WAN interface to which the address mapping rule applies.
Modify Click the Edit icon to go to the screen where you can edit the address mapping rule.
Click the Delete icon to delete an existing address mapping rule. Note that 
subsequent address mapping rules move up by one when you take this action.
