Some PTs I’m on state it’s okay to re-direct my traffic through a server to browse the site. Issue is I don’t know what software to use to do this.
I want to make a flutter app to browse forums on PTs is really why I’m doing this. I hope to bring more life into the usually slow forums.
That might be up to you, depends how much you need to do with the proxy part of that. With the seedbox provider I subscribe at they offer SSH capability so I can SSH into the seedbox. But if I want I can also create a proxy tunnel through the SSH connection & configure my web browser to use that local proxy port to tunnel through the seedbox’s internet connection. It’s not something I need to do often but is totally workable.
I do that with PuTTY, you can google around for that e.g. https://www.digitalocean.com/community/tutorials/how-to-route-web-traffic-securely-without-a-vpn-using-a-socks-tunnel is a good overview.
That said I’m sure there’s actual SOCKS proxy software you can install on the seedbox if you need more advanced features.
(don’t know anything about app development / flutter so can’t comment much on that)
