There are two solutions. 1) DNS level: Set your own DNS server, and hijiak all DNS and point to your server.
2) IP and http: When gateway gets request from client to google.com, and you can simulate “man in the middle” to syn/ack to client, and talk with client to provide 302 redirect to client. You can either use VPP host stack to get the http request.

How do I catch this http request and respond with 302 redirect that redirects user to lan ip address: 192.168.1.2:80/index.html. thanks! Happy holidays :)
