Using PIVPN, I configured openvpn on a Raspberry Pi at home. As far as I can tell ( I'm new to openVPN ) there is no administration GUI when installing openvpn on the pi.
I have a couple locations I work from: home, lab, office, remote. My overall plan for setting up openVPN is to allow me to access each of the network when I am at other networks or remote. I came across 'Introducing the LAN Turtle' video by Hak5 on youtube and I can see they configured the LAN Turtle to act as a VPN Gateway and this grants that kind of access. However, they were able to do so by using the web gui.
How would I configure a VPN Gateway on clients without using the web gui?
