I just set up a Debian server in our office. We have a business account with comcast without static IP, so I'm using DynDNS to point a domain at the machine. The problem is that I can't resolve the domain from within the network.
It is my understanding that there is no way around this using the comcast business gateway, so I would need to set up some sort of local DNS (if anyone knows otherwise that would be great).
I have a basic understanding of DNS, and I'm assuming that I need a setup that will resolve the domain to the local IP when a user is on the office network and use the global DNS record otherwise. Am I on the right track? If so, what is the best way to achieve this?
All the clients are running OSX.
