Your VPN Kill Switch Won't Stop All Leaks

I hate to think how some of those closed-source VPN provider apps are doing things. VPN kill switches are generally like comparing this with that they are all pretty bad and way over engineered trying to match a lot of use cases because of the way they are designed which largely is the same. Do agree with the conclusion though. > If you have a more advanced router (such as Unifi, pfSense, OPNsense, OpenWrt, etc.), you can configure your VPN on it instead. These routers should also allow you to set custom routes to your preferred VPN servers, acting as an effective kill switch for your whole network. This approach requires a bit more knowledge and much bigger headaches if the VPN service is down, resulting in your entire network going down. Fortunately, the risk isn’t as high nowadays because you can use mobile data on your phone to check the VPN’s service status or find troubleshooting advice. And that’s where VLAN routing can get spicy, you can have some computers on the VPN and others which are not based on the switch configuration.
