Inbound 
Mappings 
This setting specifies the WAN connections and corresponding WAN-specific Internet IP 
addresses on which the system should bind on.  Any access to the specified WAN 
connection(s) and IP address(es) will be forwarded to the LAN Host. 
This option is only available when IP Address is selected in LAN Client(s) field. 
Note 1: Inbound Mapping is not needed for WAN connections in drop-in or IP forwarding 
mode. 
Note 2: Each WAN IP address can be associated to one NAT Mapping only. 
Outbound 
Mappings 
This setting specifies the WAN IP addresses should be used whenanIP connection is 
made from a LAN host to the Internet. 
Each LAN host in an IP range or IP network will be evenly mapped to one of each 
selected WAN's IP addresses (for better IP address utilizatio
n) in a persistent manner (for 
better application compatibility).  
Note 1: If you do not want to use a specific WAN for outgoing accesses, you should still 
choose default here, then customize the outbound access rule in the Outbound Policy 
section. 
Note 2: WAN connections in drop-in or IP forwarding mode are not shown here. 
Click Save to save the settings when configuration has been completed.
