Thanks. I'll have a look at it. Maybe it's a better fit for us.

I've never dealt with RADIUS. Seems like a bit like overkill to just
get the DNS working. But I'll read up what it takes to implement
RADIUS. Thanks for the response.




Not sure how many clients you are going to have, but Openvpn allows you 
to assign an IP address to a specific client.  Look at the ipp.txt file.

Via some form of dynamic DNS perhaps? It seems it should be possible to
have the openvpn client run some script that will register its current IP
into a BIND server via RFC2136 update. Setting up BIND 9 to manage a
dynamic zone is not very difficult.
