I will check about firewalling/iptables with network administrator.
But , when I call lwip_connect(), the outgoing packet should be seen by, "tcpdump - i tap0"
Am I right?
Also I am running red hat Linux 8 on Windows XP, using VMWare. Could that be a problem?
But I am able to run normal socket based client-server sample on Linux. and also across, my Linux and XP.

Do you have firewalling/iptables configured? That could be dropping your
TAP packets.
