Expat Shield is a VPN program that allows users to access UK TV websites such as BBC iPlayer and ITV when outside of the UK. Expat Shield routes your IP address via a UK IP address as if you were still in the UK wherever you are in the world. Normally, the BBC will block any IP address that is outside the UK from accessing its services both online and through the BBC iPlayer program.
