OpenVPN and McAfee Internet Security Suite

I recently had a problem setting up OpenVPN for a residential customer trying to connect to his office network. Everything looked great and should have been working without issue. The TAP adapter would grab the expected /30 bit subnet without issue, pushed settings were applied, and the VPN logs had nothing but good report. Unfortunately something sinister was indeed going on.

Taking a quick look in WireShark I noticed that the UDP packets were being dropped. This baffled me as I had already disabled all firewalls on the machine in order to trouble shoot. Including the packaged pinche basura firewall that comes with the McAfee Internet Security Suite bloatware jamboree.

After uninstalling McAfee all problems with connecting vanished, drives were mapped, and databases were connected to.
