Use Snow Leopard’s Built-In VPN Client to Access the ITCom VPN

DISCLAIMER: This post has not been authored by ITCom and any change they make to their VPN systems may break this.

Instead of using the Cisco VPN client to access the ITCom VPN, you can use Snow Leopard’s built-in VPN client to do so. Here are the steps involved:

  1. Open the Network preference pane in System Preferences.
  2. Click the plus sign to add a new network interface.
    • For Interface, select VPN.
    • For VPN Type, select Cisco IPSec
    • Write a descriptive description.
  3. Navigate to the ITCom page to download the desired VPN profile (either off-campus or on-campus).
  4. Viewing the profile as a text file, you can see key-value pairs with the format KEY=VALUE.
  5. Back in the Network preference pane, select your newly-created VPN. Set the following values:
    • Server Address: set to the Host value in the profile.
    • Account Name: set to your uniqname.
    • Password: set to your Kerberos password (though you'll still need to enter it upon connecting).
  6. Click “Authentication Settings...”. Set the following settings:
    • Shared Secret: set to the GroupPwd value in the profile.
    • Group Name: set to the GroupName value in the profile.

Connect to the VPN and you’ll be able to access campus resources from home.

Is anyone else able to get this to work? I was able to get a VPN connection before I upgraded to Snow Leopard but now its not working for me anymore. Has anything changed?
Any ideas?

Yes, this has been working for me since before I wrote the article.

Hmmm. I just discovered that this does work for me, but only on central campus, not on north campus which is where I need it.

Any ideas?

Unfortunately we don't maintain the VPNs; that's more of a question for the folks who do:

Alrighty. Thanks anyway!

But just to clarify: you have been using this setup successfully when you are not on north campus. Correct?
This way I'll at least know if its a problem I'm having myself, or if its a problem with this setup on north campus.

Thanks again.

Yes, I have used this setup when not on North Campus.

These instructions just worked fine for me. I successfully connected from off-campus.
