How to use Squid on Linux to control certain IP to access Web Server and certain IP cannot access?

Dear all experts here,
:slight_smile:
I would like to install a proxy server on Linux server to perform solely to control the access of Web server.
In this case, some of my vendor asked me to try Squid and I have installed it onto my Linux server.
I would like know how can I set the configuration to perform the filtering of IP to access my Web server?

Thanks in advance for any help.

Without knowing a lot more about your specific setup, nobody here can really help you based on the information provided by you to date.

There are many excellent Squid tutorials available online. I recommend you read one or more of them and then come back to us with specific questions if you are still unsure how to configure your Squid installation.
