Hi all A client wants to use ISA as a cache only server. They use proxy 2 at the moment with no plans to upgrade it at present. The proxy server is in London, UK and the ISA server will be in Glasgow. The connection between Glasgow and London is a 192kb Kilostream link capable of 45k/s. My question is - how do you get the isa server to use the proxy 2 machine as it's entry point to the internet. Steve
