I have a question on using sub domains with a single static ip address. I know how to use host headers in IIS, however this does not always seem to work. I am wondering if there is software out there that can parse the host headers prior to the IIS machine and send it to the appropriate machine behind it and manage this type of traffic so I could have it send www.mydomain.com go to 1 machine and mail.mydomain.com go to another say for a mail server running webmail and ftp.mydomain.com and so on and so on. I have ISA server 2004 software but that seems over kill and I also run watchguard firebox II's between the internet and my exposed machines, I have extra hardware to place a machine between my firebox and exposed machines if this is required.
If there is a way to do this with the firebox obviously that would be ideal, but I do not think this is possible... so in a nut shell I want to be able to set up something like:
mail.mywebsite.com -> serverB
and so on.
Thanks ahead of time!
