As a general rule, if you aren't already, you should have your Linux box running a local DNS server, to which everything in your net should be pointed, and that server *should have an authoritative zone for your local RFC 1918 network number, in both directions*. If it does not, then those reverse lookups that many programs generate, in trying to log names for connections instead of numbers, will go to the outside world before they bounce... or they'll time out when your uplink is dead. This may be (part of) your problem. Cheers, -- jra -- Jay R.
