Client Authentication connection is closed after several minutes Technical Level
Symptoms
  • Several minutes after successful Client Authentication, the connection is closed.

  • Setting authentication timeouts to high values does not help.

  • Output of 'fw tab -t check_alive' command on Security Gateway shows the IP address of authenticated client in reversed order (in Hex format).

    Example:

    • Client's IP address = 172.30.10.20
    • IP address in Hex format as appears in the table = 140A1EAC (Host-byte order)
    • IP address in Hex format that should appear in the table = AC1E0A14 (Network-byte order)
Cause

Security Gateway does not send keepalive packets to the Client.
