Argonne National Laboratory

Web-Based Virtual Private Network (WebVPN)

WebVPN is a browser-based access to internal Laboratory web pages and applications. All employees with active ANL domain accounts have the ability to use the WebVPN. It does not require any additional authorization and does not require software to be installed on your computer. This is the preferred service if your access needs are limited to web pages and web applications.

After you have established a VPN connection, you can access Inside Argonne and various business applications.

However, WebVPN does not support instant messaging and certain other programs. If you wish to use these services, you will need to install the VPN client.
