Table 161   TR-098 Amendment 1: WAN Device: WANIPConnection: PortMapping: Details 

PortMappingEnabled

This field displays 1 to indicate that the port mapping entry on this link is 
enabled; otherwise this field displays 0. 

PortMappingLeaseDurati
on

This field displays the time (between 1 to 4294967295 seconds) the device 
stores the port mapping entry. After this, the entry is removed from the port 
mapping table. 
0 means that a port mapping entry is static and cannot be removed from 
the port mapping table. 

RemoteHost

This field displays the IP address of the remote host device.
If this field is blank, it indicates a wildcard which the device must support. In 
this case, when a packet is sent to the external port on the WAN, the device 
will forward the packet to the internal port. 

ExternalPort

This field displays a port number (between 0 and 4294967295) the device 
listens on for NAT connection requests. 
0 indicates a wildcard. This sets the device to forward a wildcard packet to 
the internal port.
