Chemistry Network Access from home


A VPN (Virtual Private Network) allows access to "internal" computing resources from "outside" across the internet, in a more transparent and general way than current methods of remote access (ssh, remote desktop etc.). Effectively the home/remote machine will get the same access as if it were on the internal Departmental network. 


User benefits include:

  • Easier to use than many other remote access methods
  • Once connected, any traffic routed through the VPN tunnel is encrypted
  • Windows, Mac, Linux, Android, and iOS can all use this method to connect, making configuration of remote access on multiple devices simpler

I have tried to connect to the VPN, how can I tell if it worked?

How to connect to it?

General advice

The username is your CRSID followed by - for example, a user with CRSID fjc55 should use as their OpenVPN username. For the password, you should use your ChemNet token which you can collect from .

If you are having problems with VPN (slow speeds, being disconnected) then make sure you have the latest version of the config file. We tune the settings from time to time to improve performance. Find config files and setup instructions by clicking on the appropriate link for your device below.

If that doesn't help please see our troubleshooting page.
