OpenVPN server on a machine with a dynamic IP

The need

You want to run an OpenVPN server on a debian-like system with a dynamic IP address (f.i. behind a consumer cable modem access)

The problem

You need to provide a fixed IP address in the openvpn configuration

The solution

Ensure the OpenVPN configuration is updated with each IP address change and reload the server

In order to run an application upon IP address change, you need to create a hook inside /etc/dhcp/dhclient-exit-hooks.d .
