Question

Connect with LwIP to port 5000

Hi Guys,

I want to connect a server via port 5000.

When connecting to other server with port 80 there is no problem, but when connecting with port 5000 it doesn't works.

IP_ADDR4( &remote_ip, 11, 12, 13, 14);

CommDropsTcpConn = netconn_new(NETCONN_TCP);

netconn_connect(CommDropsTcpConn, &remote_ip, 5000); --> return -14 (ERR_RST)

what do I need to configure to support connection to port 5000,? (or any port other than 80..)

Thanks,

Lior

Hello

Is remote server configured to listening at port 5000?

The RST error means that the connection was reset by the remote host.

Create a "Virtual Server" or use "port forwarding" to a remote router , to redirect "external port 5000" to an internal port eg. 80.
