Not quite sure if you still need this...
Open
Settings, select
Firewall node and select
Run in Stealth Mode checkbox, if not selected already, which may be its default setting.
Use the
Firewall Policy slider to select a firewall mode according to your requirements.

Initially,
Rules Wizard is a good starting point, which in conjunction with the
Rules auto-creation settings under
General -> ImproveNet [set this depending on whether you're comfortable with letting Outpost to auto generate rules, based on these being well-known, signed by trusted vendors, etc.] should be good to get you up and running. Note that you're facing some serious prompt activity
.

If you're confident that you're clean and there's no malicious activity present on your PC, you can switch to Learn Mode for a while to try and aleviate the pain associated with having to manually add rules. Right-click on the OSS icon in the notification area and select
Enter Auto-Learn Mode...from the context menu.
Once you're comfortable with the rules, you may consider switching the firewall policy to
Block Most, which will block anything that isn't explicitly allowed. I'm running
Block Most for both
Background and
Entertaintment Mode policy too.
