Hello,
I'm using lwIP the stack with sockets in our project to create multiple HTTP connections to a non-lwIP server. I've noticed in Wireshark traces that on some occasions the server will send a [FIN, ACK], and the lwIP stack will respond with two [RST, ACK]s, one from port 0 and then one from the correct port it was using. Is this normal behavior or is this indicative of a porting issue in our implementation?
Thanks!
