Hi We have 2 Web Interface 4.2 servers on our internal network using MS Network Load Balancing. I now have a requirement where I need to add a Web Interface Server in our DMZ for access for one of our external customers. They basically need to run 1 application on our Citrix Farm. All our Citrix components are on the internal network. We use SQL as our datastore. What is the best way to achieve this? What Ports need to be opened in the DMZ firewall for the Web Interface Server to talk to the Citrix Farm/SQL Data Store server which all reside on the internal network? Thanks Angela _________________________________________________________________ New music from the Rogue Traders - listen now! http://ninemsn.com.au/share/redir/adTrack.asp?mode=click&clientID=832&referral=hotmailtaglineOct07&URL=http://music.ninemsn.com.au/roguetraders
