The settings in PAT table correspond to the UPnP PAT table on the
router.
Service Name: Name of network server.

Protocol: Type of protocol.

Int. Port: Internal port that is mapped on the Device.

Ext. 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 in the LAN, please reasonably
arrange the ports mapping to avoid mapping to the same external
port.
When establishing a mapping relationship, please 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.
