We will only describe the process here for the Ubuntu operating system, as that is the operating system that we have been using for years to distribute our HyperV, ESXi, Amazon AWS, and Azure appliances on. If you have another operating system you can look online how to configure things exactly. We also assume that you do not use the Ubuntu program NetworkManager. If you do, and you have a GUI on your server, you may want to instead do it via the GUI. But if you have a headless server running on a physical server, or on HyperV, ESXi, and so on, you can use this guide to set a static IP address. The process is relatively straightforward, there is a text file that contains the configuration for your network interfaces. Adjust it to look like the sample below and adjust the addresses to match your network and your desired static IP. We assume an IPv4 address because at the moment this documentation section was written the Access Server only supported incoming OpenVPN tunnel connections on IPv4.
