Hello, I have LwIP Ver. 1.2.0 and the following Problem.
The device (µC) which use the LwIP have following functions. - A client (DC) in the device will connect to a PC-server (PCS) with the Port 2111). - A remote client (RC), a customer computerprogramm on WinXP, will sometimes connect to the Device-server (DS) with the Port 2111. The Problem is, that if the client (DC) will connect to the PC-server (PCS) , but the port from the PC-server (PCS) is not open or doesn't exist, i get often a timeout (because time between SYN-SYN/ACK is to long) from the remote client (RC) if i start a connection to the Device-server (DS). If the Port 2111 at the PC-server (PCS) exist it works fine, i haven't a timeout problem from my remote client (RC) and the time between SYN - SYN/ACK is short. Curios is, that if i use Win7 instead WinXP i have at rare intervals the problem. The Wireshark Log (WinXP) wireshark.out <http://lwip.100.n7.nabble.com/file/n21107/wireshark.out> Is this a LwIP problem, because of old connections? Why i get a long time between SYN - SYN/ACK --> approx. 2-3s Why is the problem extrem with WinXP? Is the time between a previous state (like FIN or RST/ACK or ...) to short before a SYN from the remote client (RC) is send? Has anyone a idea??
