[Openvpn-users] split Horizon DNS

[Eric S. J. <es...@ha...>]

running open VPN 2.1_RC19 on Windows 7.

scanned the archives a bit but didn't see any discussion on this DNS problem. In 
a nutshell, I want DNS queries to go to a name server across the VPN only if the 
query can only be served by that name server.  For example, if I'm remote, all 
harvee.org queries go to my name server on the other end of the VPN.  All of the 
queries go to the local name server.

I've had this problem on OS X, XP, Vista, Windows 7, and Linux period from some 
conversation I've seen on the dnsmasq mailing, it's partly a resolver problem. 
In any case, on Linux or OS X one can abuse DNSmasq to route queries on a per 
domain basis.  Are there any solutions for Windows seven that will let me 
resolve names on the local network as well as the remote.

Was chatting with someone on IRC and it occurred to me that a reasonable 
solution would be to build a miniature DNS proxy that would query all of the 
name servers listed in parallel and returned the answer found.  If more than one 
name server returns an answer, then the first one the search order is considered 
valid.

another reasonable solution, like I said is the dnsmasq one where you look at 
the domain name and route to a remote name server based on the domain name. 
It's a little harder to set up automatically but it's also interesting as a 
solution.

in any case, I need a solution real soon now for my Windows box.  any help would 
be wonderful.
