VPN Access in Windows

A Virtual Private Network (VPN) is a way of extending our internal network out to systems connected on the internet. Once connected via a VPN, a remote system appears to be connected locally to our network thereby getting all the facilities available to local users and avoiding blocks placed in intervening firewalls. All data passed via a VPN is encrypted.

A client wishing to connect to a VPN must first connect to the internet, for example by a dial-up or broadband connection to an ISP. Once communicating correctly with the internet, a VPN can be established to the VPN server running inside the department. Authentication must be provided in order to connect and this is the same username, password and domain which you supply to log into any central Windows system in the department.

IMPORTANT: Our VPN server supports a number of different protocols that a client can use. Generally, if your system allows the protocol to be selected then please set to SSTP rather than PPTP or `automatic`.Windows 7 and later have SSTP built in and this will make successful connections under most circumstances. However, Windows XP and the built in VPN clint in Apple OSX dont support this protocol and can only attempt connections with PPTP. This is more sensitive to firewall and router configurations so there is a fair risk of having some trouble. If using a router at home with firewalling enabled, please check that its configured for VPN access, specifically PPTP and the GRE protocol. Some people have had success with 3rd party VPN clients for OSX and Linux that support sstp and we will add recommendations when appropriate.
