How to install webmin correctly?

Question

Network administration

There is a vps located at xxxx: port . How to install webmin here if the server is already located on the port?

Answer 1

On vps.me, you will have to do port forwarding, since there is no direct IPv4. Or by IPv6 it is issued to everyone.

Answer 2

The server cannot be located "on a port".
Apparently you have access to a server on a specific protocol only that accepts connections on a specific port.
On what protocol and what port do you have access to the server?
