UC Davis Health provides remote access VPN for employees and non-employees, who are authorized to connect to the UC Davis Health network from remote locations. VPN should solely be used for conducting UC Davis Health business.

This page outlines the minimum requirements and some recommendations for connecting a computer to VPN. These requirements including the hardware, software, and the configuration are the sole responsibility of the VPN user. Refer to the Glossary at the end of this article for explanations of some of the terminology used.

Properly Configured Firewalls

The PC at the user site must have firewalls shut off or allow the proper traffic to flow through the firewall for VPN to work properly.  It is the responsibility of the user to configure their personal firewall for proper VPN operation.

Many home routers come with built-in firewalls that can block VPN connections.  It is the responsibility of the individual VPN user to properly configure their home equipment to work with the Cisco AnyConnect Secure Mobility Client. UC Davis Health will not be responsible for correcting router configurations or other non-UC Davis Health hardware. Users should contact their Internet Service Provider (ISP) for questions regarding ISP installed hardware and software and compatibility with the Cisco AnyConnect Secure Mobility Client.  Vendors and outside business entities should contact their Technical Support staff for assistance.

A Virtual Private Network (VPN) provides security for transmission of sensitive information over unprotected networks such as the Internet. VPN relationships are established between trusted sites on the Internet making the public network appear to be virtually the same as a private network to VPN members.


A device or software that can block access to the personal computer, a network or an outside connection, such as the Internet. Many home routers now have firewall capabilities. Software in this category includes BlackIce Defender, Norton Firewall, Zone Alarm and others. Window XP, Vista, and 7 have built-in firewalls.
