Mac OS X versions 10.6 (Snow Leopard) and above provide native support for connecting to the OUCS Cisco-based VPN service.
This document contains instructions on how to configure the native VPN client that comes with Mac OS X 10.6 and above. In order to use the VPN service you will also need to have the necessary Remote Access Services username and passwords - for details see the main OUCS VPN Service page.
Please make sure that you have read the introduction and general requirements, which apply to all VPN clients, before attempting to configure your computer or mobile device to connect to the VPN.
There are a number of requirements necessary in order to use the VPN service on Apple Macintoshes; these are detailed below.
2. Obtaining the prerequisite information for configuring the inbuilt VPN client
As part of the process of configuring the inbuilt VPN client you will need to
supply some group configuration information. Members of Oxford University can
download a file containing this information from the OUCS Self-Registration
and Downloads web page. Once on this page select
client from the list. On the next page that appears select
shared credentials. A window containing the information
should now pop up on your desktop. Make a note of the
secret as you will need this information later on (it will be
referred to as the shared secret) and then close the window using
the close window link.
You have now obtained the information that you need from the Self-registration web pages.
3. Configuring and using the inbuilt VPN client
To use Mac OS X's inbuilt support for Cisco VPN you will first need to open
[System Preferences], which you can do from the dock, the
[Apple] menu or by finding it in the
[System Preferences] window click the
Network icon to bring up the Network
+at the bottom of the left hand pane to bring up a dialogue window to add a new network interface. Within the dialogue window make the follow changes:

Authentication Settings... button.) Once the connection has
been established the Network window will show that the status of the VPN
interface has changed to Connected and it will display the connect time

Look for the VPN icon in the top menu bar and click the icon to bring up the drop down menu.
Simply choose the

connection. You can also use this menu to disconnect your session once you no longer
5. Further Information

If you have problems with the inbuilt client you may prefer to use the Cisco AnyConnect Client. Instructions are available from the Configuring the AnyConnect Client on Mac OS X Systems page.
