I work for a company that does IT support for other companies. I usually end up working on VPNs. Recently a customer made a change to their VPN configuration. They now assign DNS information to the VPN adapter. I used to just put my companies internal DNS as primary and googles public as secondary. This method no longer works with the VPN update. I was wondering if there is a way to point the DNS entry they provide to a different IP. Similar to how a hosts file statically assigns an IP to a host name. I would like to point the DNS entry they give me to a different IP. Can this be done through a persistent route? If not what options do I have?
