I have a rather weird issue..
I'm trying to configure Windows Firewall to block all outgoing connections to a certain app, but allow all incoming. This app is used to transfer files across a network. The reason for this type of setup is to only allow certain users (IP Address) access to the files I have, but to still allow others to see what's available.
Since Windows Firewall defaults to allowing all outgoing connections, I made a rule to deny all outgoing connections that were not in the IP ranges I specified.
For the incoming connections, I'd like to leave it at allow all, but at the moment it is set to only allow the connections that also have outgoing permissions set.
If I blanket say allow all incoming connections, I observe that unauthorized IP Address are able to actually download files, even though their IP was blocked in the outgoing connections. To shed a little more visibility on this, I used NetLimiter to see what was going on. NetLimiter showed me that the connection was an incoming connection. Shouldn't this be an outgoing connection, as I am uploading files to them, not the other way around? Is there a way to make the connection type be correct and show up as outgoing instead of incoming?
