How to create your own private IP proxy server using squid proxies

The following will allow you to run your own private proxy service for use in SEO Content Machine.

You need a VPS with ubuntu 20.04 installed and the ability to add extra IPs to your instance.

If you need a terminal client I recommend https://www.bitvise.com/

Install Squid

sudo apt update
sudo apt install squid

Check Squid is running

systemctl status squid.service

Attach extra IPs to your VPS

Luna Node example

After you add an IP a window will popup with the new network config you must use.

The specific one is Ubuntu netplan at the bottom of window. Like this…

image

sudo nano /etc/netplan/50-cloud-init.yaml

Replace content content above from Luna Node. eg…

Apply netplan

sudo netplan apply

Verify new IPs

ip address show

You should see the new IPs in the list.

Edit conf file

For each IP you add, you need to add to ACL like below.
Use internal IP, and you assign any port number you like for each proxy.

Below is sample for 2 IPs, you just need to duplicate sections and assign a different port number.

Just copy-paste the following to the top of the file.

sudo nano /etc/squid/squid.conf

forwarded_for off
request_header_access Allow allow all
request_header_access Authorization allow all
request_header_access WWW-Authenticate allow all

request_header_access All deny all

acl acid5001 myportname 5001
http_access allow acid5001
tcp_outgoing_address 192.168.30.15 acid5001

acl acid5002 myportname 5002
http_access allow acid5002
tcp_outgoing_address 192.168.30.28 acid5002

http_port 5001 name=5001
http_port 5002 name=5002

shutdown_lifetime 0 seconds
cache deny all

Save the file.

Warning: This method does not secure your proxies if someone is able to guess the IP your server and does a port scan.

You might want to add a src:
acl acid5001 myportname 5001 src xxx.xxx.xxx.xxx

To lock the proxy to be usable only from one IP. (Normally the IP of the PC where SCM is installed)

You can also setup a username password, but this is out of scope for this guide.

Restart Squid

sudo systemctl restart squid.service

Test proxies

Your proxies will be: External server IP + Port eg:

Eg: Proxies
170.75.161.99:5001
170.75.161.99:5002

You can set your browser to use proxies then visit

https://api.ipify.org?format=json

To verify that the proxy IP is being shown instead of your real IP.
