In the VPN article I posted previously I instructed you to create and use separate files for the client.ovpn config and all the keys. Because the router I used in that article puts these multiple files in a tidy folder I never bothered to combine them down to one file. Other routers can be used but I’m finding many of them want a single ovpn config file with the keys in that file. It took a little trial and error to get that set up right for my purposes but this template will get you running. Just replace the keys as noted and put your server address in the file.
