When you set router mapping
outer port, try to use port within
1024~5000, avoid using
well-known port 1~255 and
system port 256~1023, in order
to prevent conflicts.
When there are multiple
devices in the same LAN,
please plan port mapping, to
prevent multiple device
mapping to one outer port.
For port mapping in progress,
please make sure mapping port
is not occupied or limited.
TCP/UDP inports and outports
must be identical, and they
cannot be modified.
