VPN Upgrade

On Wednesday, April 30th, the VPN system will be upgraded to the latest version. This upgrade resolves the "heartbleed" vulnerability for the VPN.

Anyone who logs into the VPN ( after 7:00 a.m. on April 30th will be prompted to download and install an updated Junos Pulse plug-in.

Firefox or Internet Explorer are the recommended web browsers for the VPN; Safari and Chrome have reported issues.

From testing, we have discovered that the installation of the plug-in sometimes appears to hang once or twice. Do NOT cancel the installation when this happens. It can take up to two minutes to move beyond these points.

If you cancel the installation, you will corrupt files that then need to be removed before trying again. If the installation does not work for you, remove all versions of the NetworkConnect and Junos Pulse applications from your computer, then try to access the VPN again. You will be prompted for the Junos Pulse installation again. Let that run to completion. 

After this installation, in Internet Explorer, the security setting in your web browser for Internet sites should be set to "medium high". Also, in both Internet Explorer and Firefox, and in Java, you no longer need to have "" on your security site exceptions list. 

Note: If there are specific Dartmouth web-based systems that you would like to connect to securely, without starting the Dartmouth VPN, you can do this via Webgateway does not require Junos Pulse. However, if you use webgateway rather than, only those applications that you start from the webgateway window will be secured by a VPN connection. If you open another browser window, or start an application outside of the webgateway window, the webgateway will not be encrypting any of the information you transmit.

If you have questions or need assistance, contact your school's IT Support office or "Help" via email at or via phone at 603-646-2999.
