Hello All!
I can send TCP Packet from BBB from console:
echo " 11111" > /dev/tcp/81.23.XX.XX/5555
And it is working correct.
When I try to send TCP from c++ application, I can't connect to server(
Timeout error). Eth scheem:
BBB(192.168.1.7 -> MyRouter(static IP) -> ... -> ... ->
ServerRouter(81.23.XX.XX) -> Server(192.168.4.55)
My PC(192.168.1.2) -> MyRouter
But if I run server software in my PC, TPC packets from BBB to My PC works.
Why?
