This page covers the installation and use of the client software required to use the University of Utah School of Computing Virtual Private Network (VPN) service, found at: https://vpn.cs.utah.edu .
Accessing Web Sites via a VPN
If you only would like to access a web site on campus that requires you to come from University IP address space, or would like your traffic to be SSL encrypted to sites which only provide HTTP access, please use the campus WebVPN with your uNID. After authenticating there will be a text input box where you can enter the URL.
No client installation is required. If you would like full VPN access for all networking traffic, please read on.
Accessing the School of Computing's VPN
Currently the School's VPN is provided by the Global Protect Client of our Palo Alto Firewall. There are clients for Windows and Mac OS X. To download a client go to https://vpn.cs.utah.edu and login with your SoC Active Directory username and password. After installing the client you have three portals to choose from depending on how you'd like to tunnel your traffic:
- vpn-world.cs.utah.edu - Tunnel all traffic through the VPN
- vpn-uofu.cs.utah.edu - Tunnel only University of Utah traffic through the VPN
- vpn-soc.cs.utah.edu - Tunnel only School of Computing traffic through the VPN
vpn.cs.utah.edu is an alias for vpn-uofu.cs.utah.edu
Note that UIT also now uses the Global Protect client. Theirs is based on your uNID while ours uses your SoC username and Active Directory password. If you are switching between them you'll have to sign out via the Settings -> General tab and log in using the appropriate account for the VPN you're connecting to.
Using native IPsec clients with PSK (Pre-Shared Key)
While not officially supported, you may use your native IPsec client to access the VPN (Mac OS X, Apple iOS, Android etc.) Windows' client is not a pure IPsec client and is not supported at all. The PSK information is available after you authenticate with the VPN. Android must be at least version 4.0.3, and some kernels with 4.0.3 have a bug that cause it to not work with IPsec.
Issues with the Latest High Sierra (MacOS) Release
In the latest versions of Mac OS X, Apple Computer has changed how kernel modules are loaded. In short, Apple has an approved list of drivers and the Palo Alto Global Protect driver is not on that list. Fortunately, adding your own driver to the approved lists is a simple task:
- Boot into Recovery Mode. (Usually this is performed by holding down ⌘-R as the machine boots.)
- Open a terminal in Recovery mode.
- Enable Palo Alto's key by entering: "spctl kext-consent add PXPZ95SK77" in the terminal.
You will only have to perform this task one time. The Palo Alto driver will be recognized from that point on.
