请回答这个问题

I have a VPS oracle server, but I have encountered many problems during installation. The system cannot connect directly to the Internet through the VCN and gateway, and I have restored all the potential through the VPS. Perhaps more than 30 times, I have modified the configuration files. But just because the client is connected to Google Ping, it will be cut off: $ ping google.com ping: google.com: Temporary failure in name resolution. All DNS requests for Google are blocked, and since the DNS resolver is idle, the request is sent back to itself. We need to do only one thing: the traffic of the client's DNS is directed to the master, and the rest is directed to the master router, which does not work. But this is just a problem. Please help me install. I have installed Vulter on Google, and the speed is limited to 7 Mbps, because it is connected directly to the Internet without a gateway. Unfortunately, Timelter is not allowed, and you have not installed the Oracle server.
