Re: [lwip-users] Lwip client can't connect to another lwip server

    I find that Wireshark points to the problem usually.  If you don't
    understand the trace, show it here.

Hello,

I have two boards that I developed using STM32F1 with PHY

I used standard tcp_echoclient and tcp_echoserver codes in lwip.

That two boards connect and accept all connections coming from PC via Hercules Software.

So there is no problem on my codes and hardware.

But when I want to connect tcp_echoclient to tcp_echoserver, tcp_echoserver does not accept the request coming from tcp_echoclient.

Client state shows SYN_SENT and

Server state shows nothing

But as I said the client and server can connect to the PC successfully

What can I do in this situation?

Thanks

Murat
