We had a situation where client talks to server (both Windows machines). The server showed that there is a TCP connection open. "netstat -a" showed it as ESTABLISHED to client_ip. But when we ran "netstat -a" on client it did not show any connection to the server.
There is a firewall (physical box) between Client and Server and normally connections work.
So question to networking gurus :)
- Is it possible?
- If it is possible does it mean that Firewall or one of the switches at fault here?
PS: I am a developer and until now i did not think it is possible to have TCP connection in "ESTABLISHED" state on the Server and not to even exist on a Client.
