I have aserver that I have set up in a DMZ. It is protected on the outside by a Juniper Firewall and is running ISA 2006 on the inside Firewall. I have this server running FTP for our operations and all of that seems to be working fine. I now want to set it up to also be a Front End server for our Exchange system. Couple Questions; 1.) Do I need the Front End Exchange or can ISA 2006 handle all web email requests to the Back End exchange server? 2.) If I do need the Front End server, can I configure the ISA so it looks at the Exchange Application as if it is running inside of the internal Firewall? It seems all of the documentation recommends running the Exchange Front End inside of the ISA Perimeter, but what if they are on the same server? How do you configure that? Thanks much....this is my first post and I hope to learn much from this forum, Doug

Don't install Exchange on an ISA server, your frontend needs full access (RPC) to AD and backend servers You can have your ISA server perform FE tasks as relaying the HTTPS and SMTPstraffic but if you have more than one backend server, you can't then you need a FE Deli

Thanks....we only have one Exchange Server on the Backend. So I guess we just pass the WebEmail Traffic through the ISAto the Backend and have it handle the request. Not sure I fully understand how to configure this but let me look at that in more detail. Any info you can point me to would be most helpful. Thanks for your time, Doug

Here are some good places to start: http://www.microsoft.com/technet/isa/2006/deployment/exchange.mspx http://www.msexchange.org/tutorials/Publishing-Exchange-2007-OWA-ISA-Server-2006.html http://www.google.com/search?hl=en&rls=com.microsoft%3A*&q=isa+2006+publish+exchange+2007 Erik

Thanks for your time, Doug Just create a NONE WEB PUBLISHING rule with protocol SMTP to your backend Exchange Server That should work Deli

What do you do if you only have one server ( ISA2006/Echange 2003/AD) and wish to publish the exchange outlook web access?
