The other port is connected to another machine. While ping works between those, there are issues with tcp sonnection. TCP is getting Spurious retransmission. The issue is not with the server as it works without snort perfectly well. Also, using TCP dump I could see the response ACK being received from receiver to sender. Please if someone could help setting up this connection. Best Regards, Navdeep
