Originate an AnyConnect session and ensure that the failure can be reproduced. Capture the logging output from the console to a text editor and save. In order to disable logging, issue no logging enable. The Cisco AnyConnect VPN Client log from the Windows Event Viewer of the client PC: Choose Start Run. Enter: config terminal logging enable. As such, not all of these tips will necessarily pertain to every VPN configuration available from Cisco. However, they will give you a place to start as you work on fixing problems with your VPN.

Cisco AnyConnect is the recommended VPN client for Mac. The built-in VPN client for Mac is another option but is more likely to suffer from disconnects.

Overview

Mac Vpn

Stanford's VPN allows you to connect to Stanford's network as if you were on campus, making access to restricted services possible. To connect to the VPN from your Mac you need to install the Cisco AnyConnect VPN client.

Two types of VPN are available:

• Default Stanford (split-tunnel). When using Stanford's VPN from home, we generally recommend using the Default Stanford split-tunnel VPN. This routes and encrypts all traffic going to Stanford sites and systems through the Stanford network as if you were on campus. All non-Stanford traffic proceeds to its destination directly.
• Full Traffic (non-split-tunnel). This encrypts all internet traffic from your computer but may inadvertently block you from using resources on your local network, such as a networked printer at home. If you are traveling or using wi-fi in an untrusted location like a coffee shop or hotel, you may wish to encrypt all of your internet traffic through the Full Traffic non-split-tunnel VPN to provide an additional layer of security.

You can select the type of VPN you want to use each time you connect.
