Without the firewall everything is alright, but I want my server to be able to cope with such situations, meaning that other connections should not be affected. I will provide a Wireshark capture as soon as I can reproduce the issue. I attempt to recover at application level by closing the stale connection, but it seems that the socket still survives the close() call, as I could still see retransmissions in Wireshark. Is there another way to recover from this case without relying on a RST from the peer? I would be fine with lower the retransmission timeout, but I don't know how to do that. Daniel
