OpenVPN Installation Guide

For remote access to internal services hosted at the Institute for Advanced Study (IAS), we utilize the OpenVPN software. This software allows authenticated users to create an encrypted tunnel or Virtual Private Network (VPN) between their remote device and our campus. This has a dual purpose of protecting your traffic from malicious networks and gaining you secure access to campus resources. This access includes services like home directories, the Princeton University Library Gateway (PULIBGW), and more. This VPN is replacing our legacy Pulse Secure VPN, which will eventually be decommissioned.

Remote access requires the use of Multi-Factor Authentication. If you haven't set this up for your IAS account, please see our information page or contact the Computing Helpdesk for DuoSecurity before continuing.

The installation and use of OpenVPN will require your IAS Credentials. Make sure you fill in these fields correctly and do not include the domain of in your username.

This page links to installation guides for various devices and operating systems. Should you run into any trouble, please contact the Computing Helpdesk for more information.
