Use of the VPN has been depreciated in favour of Office 365 (Outlook Web Access) and WebDAV (Remote File Access (WebDAV)) and is now only available where staff / departments can show a clear business need to access systems from off campus that there is no other way to access.

Examples of things available without VPN:
File access (there are some exceptions)
Examples of things not possible with or without VPN
Remote desktop to PCs
