Connecting to the OpenVPN on Windows

VPN stands for Virtual Private Network. Once you are connected to the VPN, your internet 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 Desktop 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 google.com, 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.

Configuration Steps

Step 1:

Download OpenVPN for your version of Windows:

 

Step 2:

Download The CAT’s OpenVPN configuration ZIP file.

 

Step 3:

Extract the contents of that ZIP file to the directory C:\Program Files\OpenVPN\config (or to the directory C:\Program Files (x86)\OpenVPN\config depending on where OpenVPN is installed).

 

NOTE – If you are updating your existing OpenVPN configuration with a newer version provided by the CAT, we strongly recommend that you:

  • First, backup the contents of the config directory as a precaution. You can do this by copying it to a safe location elsewhere on your computer.
  • Then, delete the files in in the config directory.
  • Finally, extract the new configuration files into the config directory. This will ensure that there will not be able old configuration data left in there.

Step 4:

If the OpenVPN tray icon (computer with a lock) does not appear, double-click on the ‘OpenVPN GUI’ shortcut on your desktop.

 

Step 5:

Right-click on the OpenVPN GUI icon in the tray (next to the clock) and select ‘cecs’ > ‘Connect’.

 

Step 6:

Enter your MCECS username and password and press OK to connect.

 

If your connection has been successful, the tray icon will turn green to indicate that you are connected to the VPN.

 

Troubleshooting:
When running OpenVPN, it may be required to right-click on the OpenVPN GUI shortcut and select ‘Run As Administrator‘ in order for the connection to work correctly.
This step should not be required with the newer versions of OpenVPN.
Additionally a reboot after installing the OpenVPN may solve issues.

 

Full Tunnel OpenVPN

The default VPN configuration is split tunnel, where only data destined for PSU IP space is tunneled through the VPN. If you need to tunnel all traffic through the VPN follow the above instructions except Right-click on the OpenVPN GUI icon in the tray (next to the clock) and select ‘cecs_full_tunnel’ > ‘Connect’
