The only thing that should be in your DMZ is a web server with port 443 and 80 open through the firewall...You need can point the web server connector to a remote CF machine to render your templates....

I won't let any clients access the SQL Server unless they have a static IP Address, which I haven't needed to at this point. If I get a client with dialup that needs to access SQL Server through Ent. Mgr., I'll cross that bridge then. Not sure why you'd put the web server in the DMZ. I have just the ports needed to be open for the web server, 80, 443, 21, 8383, 8484, (both for web mail) 25, 110, 53 (DNS and mail are currently running on the mail server, but I'm moving mail to a dedicated server in the next week or so). I block all UDP traffic except to port 53 (DNS). I only open the port for my remote administration to my IP address here at home. Once I get mail moved, I'll only have ports 80, 443 and 21 and 53 open to the web server. Hopefully, I'll have the money one day for a dedicated DNS server and can close port 53 also. :) > >These other questions are more off topic but help would still be *very much >* appreciated > >2) For servers in the DMZ, is there any rational reason for them to be in >the domain?

I can't answer the appliance question, but I'm running DNS using Bind for NT. It's pretty simple and works well. You could probably get a cheap box running Linux and run Bind to avoid the cost of Windows. That's probably what I'll do when I move DNS off the web server. Hope that helped a little. -- Bud Schneehagen - Tropical Web Creations _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ ColdFusion Solutions / eCommerce Development [EMAIL PROTECTED] http://www.twcreations.com/ 954.721.3452 ______________________________________________________________________ Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists
