I set these up on cheap vps like


Install Squid Server

This will be running on a CENTOS/RHEL 7 VM with minimum specs.

Make sure to have your server up-to-date by running

yum -y update

Next, we need to install Squid Proxy by running the following command:

yum -y install squid

Once your Squid has been successfully installed you can go ahead and start the program immediately

systemctl start squid

Do not forget to enable the squid service in order to start automatically at boot.

systemctl enable squid

It is important to check on the Squid status just to make sure that everything is working fine.

systemctl status squid

You should get dialog with a saying its running..

Configure Squid to Allow your IP

You will need to edit the configuration file and add your connecting ips or ranges.

vi /etc/squid/squid.conf

How to allow a range of IP addresses to access the Internet through your proxy server

It is just as simple as adding a new ACL entry, Squid supports CIDR notation which makes the job more simple, for example, if you want to allow a range of IPs from to then you will need to add the following entry:

Find the line that starts with # should be allowed and add your ip/range below that.

acl localnet src # My new ACL

Or your work IP

acl localnet src #Work IP

Last but not least restart squid to make the change active.

systemctl restart squid

Change Squid Default Port

If you feel the need of changing the Squid default port, you just need to modify:

vi /etc/squid/squid.conf

Then find the following line and change the port

Squid normally listens to port 3128
http_port 3128

Change to that your next favorite number

http_port 1337

Allowing access in firewalld

firewall-cmd --permanent --add-port=1337/tcp
firewall-cmd --reload

There is nothing else to say at this moment if you need to go a little bit more in deep about Squid go and check out their website their documentation is pretty good.

Hope you enjoyed this tutorial and do not forget to share it.
