VPN stands for Virtual Private Network. Once you are connected, your web traffic will be directed through PSU's VPN hardware, and it will appear that you are connected physically to PSU's network. This will allow you to use private MCECS services that require a connection to the PSU network, like remote dektop and VNC.

CECS vs CECS Full Tunnel

We offer two configuration options for OpenVPN. The Full Tunnel will send all of your network communication, eg going to, through MCECS.
However the CECS or "Split Tunnel" configuration will only be used to connect to MCECS machines and resources, like the terminal server or print server.

To use VPN on a Mac you must first download the TunnelBlick client software here (opens in new window). This is a free, open source VPN connection manager for Mac.

To connect, you will need a configuration file. Download the configuration files here:

OpenVPN configuration files


These are zip files containing TunnelBlick configuration files (The extension is .tblk). Unzip the download, double-click the file labeled CECS.tblk and TunnelBlick will connect you to the CECS VPN. 

If you have selected the full-tunnel option (by loading the file labeled CECS_Full_Tunnel.tblk, your configuration should look like this:


If you're having trouble connecting, try these things.

  • Double check that Tunnelblick is installed and runs. You should see a tunnel-shaped icon in the upper right corner of the screen next to the spotlight magnifying glass when the program is running.
  • Make sure Tunnelblick is completely closed (by left clicking the icon and selecting "Quit Tunnelblick") before double-clicking the .tblk file.
  •  If you cannot load webpages after successfully connecting to the VPN, make sure "route all IPv4 traffic through the VPN" is checked in the settings.
