VPN sessions now require Duo Two-step logins. Please make sure you have Duo Two-step service enabled on your HawkID account. During the login process you will be prompted for a "Secondary password". See this page for information on what to enter there (note that page is for the Cisco AnyConnect client, but the "Second password" field works the same way on the Pulse client).
For many VPN use cases the ITS provided Cisco AnyConnect VPN service can be used.
When you are done with your session and have closed any active shares, RDP sessions, etc., press the Sign out button in the Junos Pulse application. If you do not have a Junos Pulse application running, run the application and choose sign out.
When you're done with your session and have closed out any active shares, RDP sessions, etc., press the Disconnect button in the Junos Pulse application.
