Q. What does Teardown TCP connection mean?

or Deny TCP (no connection)
or Built outbound TCP connection
or Built local-host inside

Its just that i'm new to firewalls and am trying to use the logging feature to troubleshoot connection problems.  Any advice is welcome.

    Accepted Solution

    Log Message %PIX-6-302002: Teardown TCP connection for faddr IP_addr/port gaddr IP_addr/port laddr IP_addr/port
    Explanation    This is a connection-related message. This message is logged when a TCP connection is terminated. The duration and byte count for the session are reported. If the connection required authentication, the username is reported in the last field of the message. This message is used by the PIX Firewall Manager to generate reports.
    Recommended Action    None required.
     Dent TCP does basically what it says on the tin :)
    Built outbound TCP connection means than the TCP three way handshake had been established and data can flow
     Built local-host inside (Im guessing) that the sending client has sent a SYN Packet and the firewall has placed an entry in its embryonic state table.
