Why Management interface do query instead of DNS-Proxy Interface


Hi Team,

I configured DNS proxy Interface e1/1 - to clientless vpn.

DNS-Proxy resolves as,

  1. General browsing resolves with DNS and
  2. Tutelartechlabs.com resolves with DNS and
  3. Amazon.forest.in (internal-application) resolves with DNS





DNS-Proxy interface is the interface that act as a proxy and queries for dataplane traffic instead of management interface setup-->service-->DNS.

so the question is why my management interface queries for amazon.forest.in to the DNS server when the application is accessed by a user in clientless-vpn  instead of my DNS-Proxy Interface

I have attached both pcaps from server and the firewall.

If you have correctly also attached the DNS proxy under the "Proxy" tab in the Clientless VPN then it could be a bug because you have the managment ip address in the same subnet as the data interface and I think that there was such an issue but I can't say for 100%.


Test if also configuring the service route for DNS to use the data plane interface will help or if possible to place the data plane interface in seperate subnet than the managment interface.
