External Web Server - Internal Exchange Server

[tberte]

I believe I already know the answer to this question, but it still bothers me not really knowing. I'm trying to figure our network at my place of business on my own and this one thing still baffles me.

We have outsourced our web hosting to our domain(

http://www.domain.com),

but we have our Outlook Web Access pointed obviously to our internal domain. (

http://test1.domain.com/exchange)

How are we doing this? Is this all done at the ISP level? Are these just DNS entries? or is it done through port forwarding?

This is all DNS settings.

http://www.domain.com

points to your web hosting company IP; test1.domain.com points to your company IP (eg. your front end server). I don't see any other configurations need to be done here.
