In this episode I visually explain how a VPN on a router works, using OpenWrt router, Wireguard VPN and Mullvad VPN provider. Then I show you how to set up a Wireguard VPN on an OpenWrt router. Then we test out this VPN connection using a Mullvad "check", searching for our IP address, and other status tools within the router. Using a VPN on a router has many benefits, some of which are hiding internet traffic from ISP, bypassing ISP restrictions, getting access to different content and much more. There are also drawbacks, including breaking streaming services, losing internet connection if VPN goes down (or bill isn't paid), all traffic is tunneled out through the VPN and that may not be desirable. There are many additional features you can configure with a VPN on a router, and if you're interested, drop me a comment below!

Well in this video, I’ll show you how in one foul swoop. A VPN is a Virtual Private Network that enables you to tunnel your internet connection out form a VPN server. Benefits Hide Internet traffic from ISP from all your devices (including IoT Devices) Bypass ISP restrictions Access to different content Similar to proxy benefits | Refer to the following video for more information on configuring a proxies:    • How to Create a Proxy // Squid (HTTP) and ...   Drawbacks VPNs can break your streaming services Can lose internet connection if VPN goes down Everything is tunneled through the VPN ( might not want to do that).
