As for configuring...I'm not too sure about Outpost because I've never used it but I personally go by the "deny-all" method of firewalling. That is to block all incoming traffic and start from there. If there is a certain service that needs access to your machine than allow only that service and start from there. Also allow only certain programs and services access to the outside world so as to make your presence on the net not as loud. Outpost's site has a downloadable manual in .pdf format, I'd start there for instructions on how to configure your firewall. Not sure but it might come with some security levels with matching firewall rules for you to choose from. Again, not speaking from experience with Outpost. Hope this helps.
