- Block outgoing connections and get notified, Review of Binisoft’s Windows Firewall Control Apr 12 by sekharpadikkal Windows Firewall (old school internet connection firewall or ICF) is what is protecting most of us.
- Firewall Outbound Protection is a feature of Windows 7 firewall that allows filtering of outbound connections. But this feature is half baked because once this feature is enabled, it will block all outgoing connections. The only way to allow application access to outbound connection is to create rules for them, more about this later.

One of the reasons I really like Comodo Firewall is that it makes it easy to allow or block an application from accessing the internet. Moreover, out of the box, Comodo Firewall monitors and blocks certain processes and show a warning or permission window whenever they are trying to access another process or making.

I'm trying to use Windows 7 firewall to block all outgoing and incoming traffic, from all IP's and for all protocals, except for UDP to and from one particular IP address.
The reason why is because I am using a VPN over UDP, and so no other traffic is necessary so I'd like to shut it all down.
I have configured Windows Firewall to block all outbound connections. I have then created 'allow' rules to enable certains applications to create outbound connections. Unfortunately it seems that some connections that should be allowed are still blocked and I don't understand why. I have a simple rule to allow Windows Problem Reporting: Enabled.
My configuration blocks all outgoing traffic, but also it blocks traffic going out to the IP I want to be able to access. I can't for example ping the allowed IP address (notice I have it set as any protocol allowed, so ping should work). I get 'General Failure' when I try to ping it.
I figured having the allow rule at the top of the list would make it work but it doesn't. Am I missing something here?

The proper way to accomplish this is to configure Windows Firewall to block all outgoing traffic by default, and then only allow the incoming connection(s) you want.
To do that, click on Windows Firewall with Advanced Security in the left pane, and choose Windows Firewall Properties from the right pane. Next to Outbound connections, choose Block. Then, click OK.
Once you've done that, just delete the block all outgoing traffic rule and you should be all set.
