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, reasonably arrange the

ports mapping 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.
