Outbound Connections: Allow ... Applications still blocked!
Hi All, We have a GPO that applies to all of our Windows 7 workstations stating that outbound connections are allowed. In our environment that seems safe enough. However, I still get complaints that certain outbound connections are being blocked. Today, I see on my own workstation a message that VMWare was blocked. How can that be? Here is the GPResult; below that is the FW message... TIA!

This is caused by the Windows Firewall assigning the VMware virtual NICs to the Public network.

Thanks, but my problem is outbound. Filemaker Pro 11 is another application that we found requires the addition of an outbound rule to work properly. What gives???

I never got any either, until today (after some years). vmnet0 (bridged) - all others disabled Filemaker Pro 11 - Just uses NIC on system w/o VMWare installed Also "Log file path" is a "feature" that does not work.

Hi, Every rule I have defines the program path or something else in it, but your rules look like wired. Please try to reset the Firewall Rules for a test. Juke Chou TechNet Community Support
