Ah, it seems I haven't expressed myself clearly. I was referring to the firewall's logging and tracing capabilities to analyze how, when and why the connection is broken. Besides, firewalls are capable of doing much more than blocking or allowing traffic on certain ports. They may break connections which haven't passed any traffic for a given time and are therefore considered idle - a frequent problem with Bacula through firewalls. They may limit connections to a certain duration, bandwidth, or amount of data transferred. They may intercept the content of connections and check whether it conforms to their preconceived notion of how traffic on that port looks like, whether it contains data that looks like malware (inbound) or like trade secrets, credit card numbers or social security numbers (outbound). Plenty of possibilities for interfering with applications even though their ports are allowed in the policy. -- Tilman Schmidt E-Mail: til...@imap.cc Bonn, Germany Diese Nachricht besteht zu 100% aus wiederverwerteten Bits.
