DNS Configuration issue - partly solved

A while ago I had an issue with accessing gateway machine by its external network address as discussed here: DNS Configuration issue

The solution with the local DNS server kinda worked - now there is a local DNS server with local names (machine1, machine2...) and mapping the domain names (stoynov.com) with the local addresses. It works pretty well.

The only problem is synchronizing the sub-domains (msdnaa.stoynov.com) with the local DNS server - now they should be added by hand. Kinda sucks. The good thing is that there aren't too many of them.
