University (UIS) VPN service
The UIS operate a VPN service for the University - you can find details about that here: https://help.uis.cam.ac.uk/service/network-services/remote-access/uis-vpn
Detailed instructions for setting up the University VPN
1 - Create your Eduroam Token
Getting your Eduroam Password/Token:
1.1 Go to https://tokens.uis.cam.ac.uk
1.2 For Username & Description type “vpn”
1.3 Click Create
1.4 Note down the “username” and “password” (or copy and paste them into a file). You will only get to see this once. If for some reason you miss or lose it, click Reset on the vpn entry from the list and re-create it.
2 - Configure VPN Connection
You can access internal University systems through the UIS VPN service. For full instructions any for other Operating Systems visit :
Alternatively, if you’d rather not follow the UIS instructions above, try the following (Windows 10 only):
2.1 Download this file : (Use your email address and raven password to access, not a personal gmail account):
2.2 Navigate to the file you downloaded (probably in “Downloads”), right-click it and select “Run with Powershell”
2.3 Ignore any errors that may appear but click “Yes” to Install the certificate when the pop up appears.
If the screen stays blue/blank, just click <enter> one more time.
2.4 If successful you shouldn't see anything on the screen. Occasionally a message about certificates pop ups, which is fine.
3 - Connect the VPN
3.1 In the Cortana Search box (bottom left) Type “VPN” and press Enter
3.2 Click on Cambridge VPN option and then Connect
3.3 Type in the email address obtained above (E.g. sqpr1+vpn@cam.ac.uk) and the Eduroam token you obtained above in Step 1.4.
3.4 Click OK. VPN should connect (Essentially this makes your PC part of the University Network now)
Error - Invalid Payload Received.
If you see this error when connecting VPN you may have to re-create the connection, however that's not always the case and simply trying to connect a few times is sometimes enough to resolve.
4 - Create a VPN Shortcut
4.1 Search and Run “Network Status” (bottom left)
4.2 Click Change Adapter Options (roughly in the centre of window)
4.3 Right-click and Drag “Cambridge VPN”to your desktop
4.4 Select “Create Shortcuts here”
Using the University’s (UIS) VPN from China
The University is aware that the Cambridge VPN does not work in China. This is not a technical problem and unfortunately it is not possible for the University to make it work.
The Department of Physics does not offer its own VPN that might bypass restrictions on the use of the University’s VPN from China.
