Is it possible to set up a proxy server on my PC with win 7 or a router with a white ip (or "How to make all services for instagram from one address)?

Question

Marketing

I will tell you the essence of the problem, maybe you will tell me another solution to the issue.
I need to set up a SAFE instagram account promotion for my business. Sometimes I go to Instagram from my phone (Voronezh), twice a day atoposting takes place through a separate service that uses its own servers, and during the day another service is engaged in setting likes for competitors' subscribers. In total, 3 different resources create activity on one account, this is bad.
Auto-like and posting services have a proxy setting. I can send them through one purchased proxy, but from the phone (ios) I will still be from another city. The phone has a VPN setting, and only a proxy in the services.
Hence the thoughts are, if I could set up a proxy on my own equipment, then I would allow posting and likes through it, and the iPhone would create activity from this IP anyway. But I did not find a single source where this would be described, is it real?
Available white static ip.

Answer 1

Because there is no way to configure all software to go through a proxy, then you need to use VPN instead. The VPN option does not depend on software support, it works at a lower level. You need a VPN option that is supported by all the platforms you work on, such as OpenVPN.
The rest of the diagram is correct.
It would be more convenient to rent VPS/VDS servers for VPN. In this case, you will need to set up NAT on the VPN server, but this is not a problem.

Answer 2

Yes, but it's easier to buy
