VPN on a VPS
Your own VPN server: WireGuard or OpenVPN on a rented VPS.
Running your own VPN on a VPS is a popular task: a server in the country you need, your own address, no shared limits. One core and 1 GB of memory are enough.
What matters is KVM (otherwise WireGuard may not start), bandwidth and traffic. Check the provider's rules before buying: some forbid VPNs for third parties.
