Hi<br />
I currently have three remote offices soon to be four, the main office has a cisco 5505 as the firewall linking the remote offices via VPN .<br />
My question is I need to install TMG mainly for use as a proxy server although i do understand it does a lot more, but will need time to learn how to use it and my offices are already up and running and I need a proxy sooner rather than later, is this a possible?
