The new VPN system is provided by Palo Alto GlobalProtect and is the same for both Microsoft Windows and Microsoft Surface computers. In order to use this you will have to download and install the client to the local PC. Once installed, you can log into the VPN using your UTAS username and password to access the network as if you were on campus.
You need to have installed the client on the PC you're using in order to connect. You will also need to have an active Internet connection to the PC.
