Hello people, I have a couple of contractors coming in next week and they want access to a Citrix server located on their own site. I have enabled the relevant Citrix protocols through a site and content rule and this has worked before no problem, but only if the machine is on our own domain. We have authentication outgoing enabled on the ISA server as well. I wondered what was the standard procedure for allowing an outsiders machine sitting on the lan access to the outside world using what ever protocols (in this case Citrix) without joining them to your domain or downloading the firewall client to their machine ?
