My department is set up for Stanford University Network Access Control (SUNAC). How do I log in?

Incorporating VPN, Workgroup Manager, and Firewall services, the SUNAC service provides an additional degree of authentication based on a user's SUNet ID providing granular access to local departmental resources, something not possible with the current Public VPN.
