Can I run a VPN on a NAT VPS, or do I need a dedicated IP?

You need a dedicated IP. A VPN listens for inbound connections on a UDP port and routes your traffic out under the server's IP — that requires your own public IP and the ability to open ports, which a shared-IP NAT plan doesn't give you. Pick a dedicated-IP plan for a VPN.

Is a self-hosted WireGuard VPN better than a commercial VPN?

For privacy from your network and a fast personal tunnel, yes — you control the server and there's no shared-logs question. But be honest about the trade-off: all your traffic exits one fixed IP that's clearly a server, so it's great for privacy and geo-flexibility, not for blending into a crowd. And there's exactly one location — yours.

How fast is WireGuard on a VPS?

Fast. WireGuard adds very little overhead, so you'll usually get close to the server's line speed — far snappier than older OpenVPN setups. On a small box the CPU is rarely the bottleneck for a personal tunnel.

Does a VPN need a lot of RAM or CPU?

No. A personal WireGuard tunnel is light — a 1 GB / 2-core box handles several devices comfortably. WireGuard lives in the kernel and sips resources; you're paying for bandwidth and the IP, not horsepower.

Will my self-hosted VPN keep logs?

Only if you set them up — WireGuard itself doesn't log connections or traffic. Since it's your server, you decide. That's the core appeal: the 'no-logs' promise is something you enforce, not something you have to trust a company on.

Self-host your own WireGuard VPN on a VPS

There's a particular itch a commercial VPN never quite scratches: you're still trusting someone else's no-logs promise. Self-hosting WireGuard flips that — the server is yours, the keys are yours, and the only no-logs policy that matters is the one you actually configured. It's also genuinely fast and takes about ten minutes. Here's the whole thing.

First, the one requirement people miss

A VPN needs a dedicated IP — not a NAT/shared-IP plan. The reason is simple: a VPN listens for inbound connections on a UDP port and sends your traffic back out under the server's own address. That needs your own public IP and the freedom to open ports. A shared-IP NAT box (SSH on a forwarded port, no arbitrary inbound) can't do it. So pick a dedicated-IP plan before you start — everything below assumes one.

It doesn't need to be big, though. WireGuard is light: a 1 GB / 2-core box tunnels several devices without breaking a sweat. You're paying for the IP and bandwidth, not CPU.

Install (the easy path)

On a fresh Ubuntu/Debian dedicated-IP box, the quickest route is the well-known wireguard-install helper script, which handles keys, the interface and the first client for you:

sudo apt update && sudo apt install -y curl
curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
sudo bash wireguard-install.sh

It asks a couple of questions (public IP — it usually autodetects, port, DNS), then generates a client config and shows it as a QR code. That's the whole server side.

Prefer to do it by hand? The manual version is just: apt install wireguard, generate a keypair with wg genkey, write /etc/wireguard/wg0.conf with your [Interface] and a [Peer] block per device, enable IP forwarding (net.ipv4.ip_forward=1), and systemctl enable --now wg-quick@wg0. The script just does this for you without typos.

Connect a device

Phone: install the WireGuard app, tap +, scan the QR code the script printed. Done.
Laptop: install WireGuard, import the .conf file the script saved. Toggle on.

To add another device, re-run the script and choose "add a client" — each gets its own config and key.

Don't skip: lock the box down

It's a VPN, but it's still a server with a public IP getting scanned. Spend the five minutes on the security checklist first — SSH keys, no password login, a firewall that allows only SSH and your WireGuard UDP port. A VPN on an unhardened box is a contradiction.

The honest trade-offs

Self-hosting wins clearly on trust and speed: your server, your keys, WireGuard's near-native throughput, no logs unless you make them. Where it doesn't win:

Anonymity in a crowd. All your traffic exits one fixed IP that obviously belongs to a server. That's excellent for privacy from your local network or ISP and for a stable personal exit — but it's the opposite of disappearing into a shared pool. Different goal.
One location. You get the region your server is in, full stop. No country-hopping.
You're the admin. Updates, uptime and key management are now your job — which is exactly the point, but it is a job.

If what you want is a fast, private tunnel you fully control — for your own devices, your own traffic, no third-party trust — self-hosted WireGuard is hard to beat. Grab a dedicated-IP plan (you can pay in crypto, no KYC), run the script, scan the QR, and you're tunneling in about ten minutes.
