Parameter Description
Port Mapping
List
The settings on port mapping list correspond to the UPnP port mapping
list on the router.
●
Service Name: Name of network server.
●
Protocol: Type of protocol.
●
Internal Port: Internal port that is mapped on the Device.
●
External Port: External port that is mapped on the router.
●
To avoid the conflict, when setting the external port, try to use the
ports from 1024 through 5000 and avoid popular ports from 1
through 255 and system ports from 256 through 1023.
●
When there are several devices on the LAN, properly arrange the
ports mapping relations to avoid mapping to the same external port.
●
When establishing a mapping relationship, ensure the mapping ports
are not occupied or limited.
●
The internal and external ports of TCP and UDP must be the same
and cannot be modified.
●
Click to modify the external port.
