Hi all, I have been trying to set up ISA so that when a client outside hits it with a particular url, the ISA Server re-directs to an internal web server. eg: aaaa.domain.com ---> webserver1 bbbb.domain.com ---> webserver2 cccc.domain.com ---> webserver2/directory This works fine if you are re-directing to one web server, as you don't need to use a detination set, but once you do more than one and start using destination sets, clients get "403 Forbidden" errors back from ISA. Have followed the help guide at the isaserver.org learning zone exactly on publishing multiple websites, but the problem still occurs Help! Thanks, Chris
