I am trying to build a Back to Back DMZ and for the moment all I want in there is a ftp server and a web server (apache). So I built the external ISA server made sure I could access the internet (note this box nor the server are in a domain they are in a workgroup) then I built the FTP server and, I then publish the FTP server, through server publishing and added a few packet filters, that worked great, a huge stroke of luck. Then I tried the apache web server and I just could not publish it. Problems that there may be. 1 we are not in a domain 2 we will be accessing the site by ip not by dns res ie 123.123.123.12 not www.???????.co.uk <http://www./???????.co.uk> and arrrgggggg I am tired any suggestions would indeed be welcome Robbie
