thanks for reply.
It's not an IP problem, my real device and client computer are all connected
to local network through a WIFI router, they can connect to each other
directly. My phone has IP address: 192.168.0.176 and computer's IP is
192.168.0.126, assigned by DHCP.
I found that if I establish any connection from my phone to computer before
I start to listen on port, then my phone could be successfully noticed that
there're incoming connections and of course, accept them.
Why it has this strange network connection behavior?
thanks a lot
