 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.
