Give it an obvious name like “Use VPN Only”: In our case, we’re going to take utorrent as an example. You now need to create rules for your application(s) so that they only use the VPN and that when if the VPN connection drops, they stop whatever they were doing. Now go in Comodo > Advances properties > Network Zones and create a new zone that you’ll call “VPN” for example and add the TAP32’s MAC address as the type. Open a command prompt and type ipconfig /all. The best way to do this is to use the TAP32’s MAC address. Deactive them if you wish then set the Firewall to Custom Ruleset:Ĭreate a new network zone for our VPN. Once CFW is installed, it installs a load of other functionnalities that I personnaly didn’t really want like HIPS. I achieved this using Comodo firewall but you might be able to achieve it with other free or commercial firewalls.ĭownload and install Comodo personal firewall from here: So I thought I’d learn doing something I know firewalls are capable of by creating specific rules that would cut an application off from the web should the TAP32 adapter loose its connection. I used this feature mostly with utorrent, however it sometimes happened that the VPN would drop several times in minutes and i’d end up with dozens of remaining utorrent icons in the taskbar. This program has a useful feature that can open/close specified applications if your VPN connection drops (which does happen every now and then). I have been using a VPN service called PrivatVPN for the past year that seems to be one of the few VPN services that offers a free software to manage your VPN connection.
