Try turning on the LWIP_DEBUGF statements.  You should then get a reason
for the reset in the form or a print statement.

The most likely one from what you describe is the reset sent at line 628
of file lwip/src/core/tcp_in.c.  This is triggered if the ACK in the SYN
handshake has the wrong ACK number, but from the trace you provide that
doesn't seem to be the case.
