Home VPN Server & Travel Router

I want to browse safely from any hotel or coworking space by tunnelling all my traffic back to a small VPN server that will live in my house. The job has two parts:

• Hardware advice – point me to a compact, reliable travel router and the best-value home server (could be a Raspberry Pi, mini-PC, dedicated router or NAS) plus any cables, power adapters, or memory cards I should add to the shopping cart.
• Full setup – install and configure the VPN on the home unit, flash/configure the travel router, and hand me clear, copy-paste-ready instructions for connecting both my laptops/desktops and my iOS/Android phones. Secure browsing is the main goal, so strong encryption, a clean firewall policy, and DNS leak protection are mandatory.

I’m flexible on protocol; if OpenVPN, WireGuard, or another option suits the hardware better, explain why and go with it. Once everything is up, we’ll run a live test while I’m on a public Wi-Fi network to confirm that all traffic routes through the tunnel and that speeds stay reasonable.

Deliverables
1. Shopping list with purchase links and brief justification for each component
2. Step-by-step build and configuration guide (terminal commands, screenshots, or short video)
3. Finished configs/files so I can re-flash if needed
4. Remote test session demonstrating working VPN from laptop and phone

The solution should be maintainable without a monthly subscription and easy to update if new firmware arrives.
