Hi all,
I have a very strange behavior of internal DNS Server (Windows 2012) with split DNS when user is connected over VPN (Cisco AnyConnect).
When I do nslookup on the server the DNS server is properly recognized and answers properly both for internal domain (domain.local) and external domain (domain.com) configured on the server as another lookup zone (split DNS). But when I do the same on the client
connected over VPN, nslookup properly recognizes Windows 2012 DNS server, properly answers for queries related to internal domain but returns Non-existent domain for external domain.
What could be the reason for such behavior?
Thanks in advance for any tips.
