Installing
To set it up on Windows , download and run the appropriate OpenVPN installer for your version of Windows. At the time of writing, there is a direct link to the Windows 10 installer at https://build.openvpn.net/downloads/releases/latest/openvpn-install-late... .
- You may be asked if you want to allow the program to make changes to the computer: select "Yes".
- You will be shown a "Welcome to the setup wizard" screen: click "Next".
- You will be asked to review the licence agreement: Click "I agree."
- You will be asked to choose components. Leave all the components ticked and click 'Next'.
- You will asked to choose a location for OpenVPN. Accept the default and click 'Install'.
- You may be asked to approve the installation of a TAP adapter. If so, click 'Install'.

- You will be given the option to show the 'README' file. Click 'Finish'.
To configure OpenVPN to connect to the Chemistry department:
- Download this config file and this dummy credentials file . (Right-click the links and select 'Save Link as...' and save to the hard disk).
- Copy the files into the OpenVPN config directory. If you installed the program to the default location (c:\Program Files (x86)\OpenVPN), that directory will be c:\Program Files (x86)\OpenVPN\config\ . In the latest versions of the program you can also save the config files directly into your personal space at C:\Users\<your username>\OpenVPN\config . You will need to edit the dummy credentials file - see next bullet point.
- Edit the credentials file in Notepad or another text editor. Replace the dummy credentials with your username and ChemNet token. You can collect the token from https://apps.ch.cam.ac.uk/ssms/collectchemnet . The username is your CRSID (in lowercase) followed by @ch.2018.cam.ac.uk .
- Please note: if OpenVPN does not succesfully log in, try manually typing your ChemNet token in the credentials file as copy/pasting from the webpage does not always work
Connecting
To connect to the department, find the 'OpenVPN GUI' start icon and doubleclick it. An icon of a white computer screen will appear in the system tray. Right click that icon and select 'connect': you will be asked for your Admitto credentials. A window will pop up showing logs as the connection is made. When the VPN is connected, the system tray icon will change to have a green line around the computer screen.
