The real lesson is here: > I am not a fan of making a VPN connection on your only router, but suggest having a second router dedicated to VPN connections. When you need a VPN, connect to the second router (Wi-Fi or Ethernet), when you don't need a VPN, connect to your main router. Aka, don't use a device with two network sockets if it is critically important to avoid using one of them.
