There is a fixed timeout of 8 hours after which your VPN connection is disconnected. There is also a non-activity timeout of 20 minutes which takes effect if no network traffic passes for 20 minutes. If you have a legitimate requirement for a VPN connection which is not subject to these timeouts, please contact account-services@slac.stanford.edu to request an exception. Your VPN will also be disconnected if your system goes to sleep. IT Department Support can assist you if you need to adjust the sleep settings of your system, they can be contacted at ithelp@slac.stanford.edu .
Can I connect to the SLAC VPN using my mobile device?
There is an app for iPhone and iPad which some users have had success with. It is unsupported at this time, but you are free to make your own attempts to connect using it. Search the app store for "Cisco AnyConnect Client". Within the app, select "Add VPN Connection...". Enter vpn.slac.stanford.edu as the server address, this will be replaced with a list of the VPN servers that is automatically updated each time you connect.
