When you connect to the VPN, your computer establishes an encrypted link to CAEDM and becomes part of the college network. You're able to access resources as if your computer was hooked in to the college network here on campus.
When to use the VPN
Most CAEDM remote computing resources can be used off campus without using the VPN. The VPN is needed only to access resources that are designed specifically be available exclusively on-campus, either for security or licensing reasons. By design, most computers in research areas, faculty and staff machines, and other computers not intended to be accessible from the internet are behind a "firewall", protecting them from attacks on the internet. The VPN makes your off-campus computer appear as if it were on-campus, making these additional computers reachable.
As seen in the table above, the VPN will allow off-campus connections to map a J Drive, or to print from off-campus to a CAEDM lab printer, but is not necessary for reaching RGS, Citrix, or SSH. It is also not necessary for reaching CAEDM hosted websites. Note that using the VPN will not grant you any additional access while using BYU Guest Wireless.
Protocols
There are two ways of connecting to the college VPN. The first method uses PPTP (Point-to-Point Tunneling Protocol) and is the recommended way to connect; the second method tunnels a PPTP connection through an L2TP (Layer-two Tunneling Protocol) connection.

- Click 'Create'
- Once you select 'Create,' it will bring you back to the main window where you will be able to alter the settings. For server address, type 'fortress.et.byu.edu' for Account Name type your caedm username. Select Automatic Encryption.
- Make sure 'Show VPN status in menu bar' is selected. It makes it a lot easier to connect to CAEDM in the future.
- Hit the 'Authentication Settings..." button.
- Select Password and enter your CAEDM password. Press 'OK'
- Hit the 'Advanced..." button.
- Select the 'DNS' screen. Add the following DNS address: 128.187.48.2

- A small lock will also appear next to the network icon in the top right of the menu bar.
Troubleshooting
- If you are going to be using programs installed on your local computer that require a licence server, make sure that you include the et.byu.edu extension.
Example: Wizbang 2000 requires a licence server to run. Normally, that licence server would be set to something like "1234@licserv", when using the VPN, it needs to be "1234@licserv.et.byu.edu". This will route the licence request through VPN, and will then be able to find the licence server. You can add the et.byu.edu and it will work just fine on campus as well, in addition to off-campus locations.
- You cannot currently use L2TP on Windows 7
