Maths VPN Service


  • When working remotely, you may find that there are resources you need to access and cannot because they are blocked at the Maths firewall. For example the Mathematics administrative database.
  • Accessing your home directory and other files used in your work is more difficult from off-campus.
  • There are still websites around which restrict access by IP address (though this is becoming less common).

The use of a VPN (Virtual Private Network) can help with these problems. While connected to the Maths VPN, your computer is effectively inside the firewall and is advertised as having the Maths VPN server's IP address.

Caveat - ejournals

It should not be necessary to use the VPN to access ejournals, and if you are a visitor and have not been granted off-campus access, doing so is in violation of the JISC Model Licence. If you are a current staff member or student and there is a journal you can only access on site or with the VPN, please report the problem using the "ejournals and eresources problem report form" below.

We log your connections and disconnections from the VPN. While you are connected we also log your network traffic (this includes the IP addresses of the machines you connect to and the network port you connect on, but not details of the specific web pages you visit, nor anything about your email except that your computer connected to such-and-such a mail server at such-and-such a time). This is required by the UIS because otherwise, if there were an issue with a rogue VPN client, we would only know that a machine using the VPN server's IP address was causing trouble on the network, and we would have to shut the VPN down until the issue was resolved.

The logs are kept for 4 weeks, they are only accessible by Computer Officers, and we only look at them when there is a problem, we are trying to trace a bug or we suspect misuse.
