I'm creating a virtual private cloud as a development environment. Right now there is just a single server running OpenVPN, BIND and Subversion at IP 10.0.0.100.
If I pass along push "dhcp-option DNS 10.0.0.100", then clients can resolve the cloud resources by name (svn.example.dev = 10.0.0.100), but then they can't resolve local DNS names on their own network (e.g. desktop1.example.local).
How can I "add" instead of "replace" dns servers for clients? Or am I now going about this all wrong and I should have a single DNS server that they both access?
