Hello,
For that you need small Linux skills.
This is the best way to manage your ip's and cheaper way.
I recommend using OVH for that. Have many ip's and very cheap:
1. You order VPS from OVH for 5USD/m (
https://www.ovh.com/ca/en/vps/vps-ssd.xml).
2. You order additional ip's for 3USD (1 time setup price)
https://www.ovh.com/ca/en/vps/vps-geolocation.xml
Quick Guide:
1. You install on you VPS Debian 9.x
2. You attach ip's to VPS in OVH panel
3. You add ip's to Debian OS editing file /etc/network/interfaces (
https://wiki.debian.org/NetworkConfiguration)
4. Install squid Proxy: (set user & password to access proxy)
Code:
apt-get update && apt-get install apache2-utils squid3 -y && htpasswd -b -c /etc/squid/passwd [PROXY_USER] [PROXY_PASSWORD] && wget -O /etc/squid/squid.conf https://raw.githubusercontent.com/hidden-refuge/squid-proxy-installer/master/spi-ubuntu.conf --no-check-certificate
5. Config squid:
A. dns_nameservers [DNS SERVER IP] >> use
https://public-dns.info/ to find close DNS server
B. http_port [XXXX] >> Port to proxy, don't use 80,8080 use random number that way sniffer can't see that u are a proxy server.
C. auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid/passwd
Set where to search for user&pass file.
D. Setting mulit ip's address:
acl 1-1-1-1 localip 1.1.1.1
tcp_outgoing_address 1.1.1.1 1-1-1-1
You will set this 2 line for every ip address u have in
VPN. that mean that mean ip u use to connect to proxy will be the ip the proxy will use to go out.
D. service squid restart
Now you are good to go.
Connect what ip address u want to use, with proxy, then enter user&pass.
You can check proxy here:
https://whoer.net/ https://proxy6.net/en/privacy
If you like it, tell me. Then next manual will be how to set anonymous firefox for every account using this proxy and getting 100% score in whoer & proxy6
This is how it looks
Best way to get dedicated ip's in EU & CA (Using anonymous proxy and not VPN)
