I'd like to block all outgoing port 80 activity except for one particular application.
Why? I want to test a piece of software to see if it will fall back to a proxy if a direct connection to the web is not available. I need to allow my proxy to connect, but nothing else.
I would have thought this would be a comon scenario, but I'm not able to find anything that gives a hint as to how to accomplish this.
BTW, this is on Windows 7
You can accomplish this by using the Advanced Security settings panel.
Open up the Windows Firewall Control Panel item and click "Advanced settings":
(You can also open Advanced Security by opening the Start Menu and typing "Windows Firewall with Advanced Security".)
Click on Windows Firewall Properties:
Select "Block" from the "Outbound Connections" menu:
Click OK, then create a new outbound rule. Click on Outbound Rules (in the left sidebar), and then click on "New Rule":
I had the same problem and hope freeFirewall application solve it. My connection's bandwith is too low so when I play online games I needed to block all other applications. But this app has Gaming mode which I hope to do the job.
Install it from their website
