How to Use VPN on Windows Vista/XP/2000

If you use the client download from this website, the configuration should be preset and usable immediately. If for any reason this is not the case or you have downloaded an earlier client version, call the IT Service Center at 303-735-HELP (5-4357 from an on-campus phone) or uninstall the old client and then download and reinstall the latest VPN client from the Downloads and Instructions page.

1. Run the Cisco VPN Dial application. It should be located under Start --> Programs --> CU VPN Client. Select CU VPN Dialer.

2. Choose the connection entry that applies to you, and click Connect.

Connecting from Off Campus:
This profile is not accessible from ANY on-campus location including ResNet and any secondary subnet types. You should use this profile only if the IP address you are coming from does NOT begin with 128.138.x.x, 198.11.16-31.x, 172.20.16-31.x, or 10.x.x.x (unless you are definately off campus with this address).

Connecting from On Campus:
This profile is available to all on campus users. It is primarily in place to secure data over the otherwise insecure wireless connection. If you wish that your internet traffic not be viewable to anyone nearby, use this connection.

Connecting from ResNet:
Accessible to all ResNet users including the residence halls, family housing, and ResNet administration. This connection is recommended for wireless users to secure all internet traffic that would otherwise be visible.

3. A new window should appear asking for your username and password.  Put in your CU Login Name and IdentiKey password, then click OK.

4. The VPN should now provide a secure, encrypted connection to the CU Network. You will know you are connected by the small lock to the left of the connection, and the lock in your taskbar. 

5. You can disconnect at anytime by clicking the Disconnect button in the VPN client.
