The School of Computing uses OpenVPN

If you have an account on the CS domain, you may access campus resources through our VPN server.

IMPORTANT NOTE as of Fall 2018, you must have OpenVPN 2.4.X or later installed or your connection will fail to connect. If you get a fail to connect message, uninstall your version of OpenVPN and install the one below. If you have a MAC, make sure you are on 2.4 or later.

Windows

  1. Install: OpenVPN-2.5.0.I601-x64.exe or OpenVPN-2.5.0.I601-x86.exe

  2. Run OpenVPN GUI as administrator This is required or your connection will not work.

  3. Right click the icon in the system tray and click connect
  4. Enter your CS username and Password
  5. If you have problems try again running the program as administrator

OS X/Android and others

For Mac:

  1. Download and install Tunnelblick from https://tunnelblick.net/ or use your favorite OpenVPN client

  2. Download the .opvn file Mac2022.ovpn

  3. Double-click the .ovpn file. This will add the configuration to Tunnelblick.
  4. Connect or disconnect using the icon running on the right side of the menu bar.

For Linux/Android/Others:

  1. Ubuntu and somewhat generic instructions

Troubleshooting

Problem: Your connection yo-yo's up and down every 60 seconds.

Solution: You are connected to the VPN with two computers using the same account. Disconnect from the VPN on one of your computers.


Problem: You want to use the VPN for traffic that goes to the school, but not for any other traffic.

Solution: Add the following lines to your config file.

pull-filter ignore "redirect-gateway" 
route 10.10.0.0 255.255.0.0 vpn_gateway 
  1. Does not consider the server redirect-gateway in order to avoid all traffic through VPN Gateway
  2. Re-add the CS network you need to reach from client through VPN Gateway
