VIRTUAL PRIVATE NETWORK (VPN)
The Cisco AnyConnect VPN software used for OWL can also be used on other networks. For instance, a 2nd year linguist who is overseas and need to access Journals, or when you are in a “sketchy” coffee shop with “free” Wi-Fi zone. You can use VPN to give you a more trusted connection into the Oxford network or simply to access certain “Oxford University ONLY” services or Journals.
What is VPN anyway?
VPN (Virtual Private Network) is a secure “tunnel” connecting two computers together so that they appear to be in the same location, even though they may be many hundreds of miles apart. It is like running a single continuous cable from your computer at home (or overseas) and plugging it into the University network.
While connected to the University AnyConnect VPN, all your Internet traffic goes through the Oxford connection. You are therefore bound by the University and College IT Rules and Regulations until you close the connection.

A word about Split Tunnelling VPN
The University AnyConnect VPN passes ALL Internet traffic through the VPN servers in Oxford; therefore, you will be bound by the University and College IT Rules and Regulations. However, for completeness of this blog post there is another way to configure a VPN connection which you may come across called Split Tunnelling VPN – an example is the enterprise class software called GlobalProtect by Palo Alto.
Split tunneling is network concept which allows a user to access different security level networks at the same time – for instance a public network (eg The Internet) and a corporate Local Area Network (LAN). A connection is usually through simultaneous use of a network card or wireless adapter, and VPN client software. An example would be, a user using a VPN client to a business network whilst using a hotel Wi-Fi network. The user with split tunneling enabled will be able to connect to the business file and database servers on the business network through the VPN connection. However, when they attempt to access external websites (eg BBC News website or Netflix), the web request goes directly out to the web service through the hotel network.
