WebSep 1, 2012 · 2 Answers: 2. TCP is a bi-directional protocol. This means that during a connection close sequence, both sides get to say "I'm done sending things now." The connection isn't "down" until both sides have done that, or one side sends a TCP RST packet. It is quite possible — and indeed common — for the connection to be half-closed. WebJan 5, 2024 · Most often, there is a problem connecting and sending data in general, especially ACK RST. If you see a SYN packet pass through the packet filter, if it is logging that rule, you can rule out the packet filter as the root cause of the problem.
WebJul 3, 2013 · 5. TCP is a connection-oriented protocol meaning it first sets up a connection to the receiver then sends the data in segments (PDU for transport layer) which is carried by IP packets.

WebSYN starts a connection; you'll usually only see it when the connection's being established. But all data being sent via TCP requires an ACK.
