CS Wall is our VPN service which is available to both staff and student users of Computer Science.
The aim of this service is to provide secure and private communication to CS network services from remote locations.
To use the CS Wall service you must have a CS user account. Staff have access to staff network services whereas students have access to student network services only.
It is important that your system is protected against security threats and the pages below offer further advice:
- Windows – 7/8/8.1/10 (for both 32 bit and 64 bit clients)
- Mac OSX – 10.5 and earlier to 10.6 and above
- Android and iOS Devices
- Windows Mobile Devices
- Linux – Centos and Scientific Linux 5,6,7 and Ubuntu 14.10, 15.04
Configure your personal firewall
If you have a personal firewall, you may need to open these internet ports. You should be able to create a customised rule for these services:
TCP port 80
TCP port 443
You may have to contact your ISP (Internet Service Provider) if these ports are blocked on your wireless router or if they are blocked centrally by the ISP.
Please refer to your firewall’s help files, as rule creation methods differ between applications.

Q: I have upgraded my Windows to Windows 10, will the client for Window 8/8.1 work on Windows 10?
A: Follow the instructions under the Windows section above to download the latest client (for Windows 10).
Q: I was connected to the VPN client on my Windows 10 and it was working fine. But now when I am trying to connect I am getting this error: “VPN connection cannot be established as the modem is not found”
A: The only solution to resolve this problem right now is to restart the PC. This error occurs when a Windows System goes to sleep mode abruptly or if the previous connection is not terminated properly.
Q: I was able to download and install the client properly but when I am trying to connect I am getting this error: “VPN Server not reachable”
A: Please check the following:
- Your personal firewall settings and make sure the ports 80 and 443 are not blocked
- Check if your antivirus program has any firewall that is blocking the ports above
- Check that your wireless router or ISP (Internet Service Provider) is not blocking ports 80 or 443
Q: I am connected to the VPN but I cannot connect to my home drive.
A: While connected to VPN use an FQDN (Fully Qualified Domain Name) to connect to a Windows share. For example you cannot access your home drive as \\smbhelp\userid but rather you should use \\smbhelp.cs.ucl.ac.uk\userid
Q: I am still using Windows XP and is there a VPN client available for Windows XP?
A: Windows XP is not supported by Microsoft and therefore considered a security risk. You must upgrade to at least Windows 10 before using the VPN.
