Can the Internet reproduce a regulated environment at hand?

I would like to build a VPN server in a local network environment, assuming that the Internet is regulated.

Specifically, the following regulations are expected:

DNS not available
Cannot connect to a specific IP

The purpose of this is to ensure that all network communications can be made through an external VPN server using a VPN client.

ASK:

I would like to reproduce this environment to verify Internet connectivity over VPN.Do you have the right tools to recreate your environment?

How to verify successful connection from China to verify VPN operation: How can I verify VPN connectivity in China? The answer is using IaaS from China.As this question is not intended to validate connectivity in China and is there a technical way to build such a regulated environment locally, I do not think it is a duplication for now.

Connect the Internet to the local network using a Cisco router (Cisco router in the U.S.).
You can configure IPs that deny connectivity on the router, which can cause situations where you cannot connect to the IPs of certain IPs or DNSs.Extremely speaking, you can also disable communication with non-IP on the VPN server.

It doesn't matter if it's not a Cisco router (even a non-Cisco product), but Cisco is the world's largest manufacturer of network equipment with a wide variety of products and easy access to documentation, such as the Cisco Certified Technician text.
