Need advice on setting up a reliable VPN that works across laptops, smartphones, and a home router. I'm interested in the core concepts: which protocols (e.g., WireGuard vs OpenVPN) offer the best balance of speed and security, how to handle DNS leaks, and whether split tunneling is worth enabling. Also curious about optimal server placement for balancing latency versus privacy, and how to securely manage credentials across multiple devices. Any thoughts on self-hosting versus using a third-party service, and what key settings you always double-check? Would love to hear your go-to checklist and any pitfalls to avoid. 🙏

I have high requirements for stability, security, and ease of use with multi-device VPNs. I’ve personally set up a self-hosted solution using WireGuard + AdGuard Home + Unbound and want to share my core experiences:
First, when choosing a protocol, I immediately ruled out OpenVPN because establishing connections on mobile devices takes too long, and background wake-ups are a disaster. If your network only has desktop-level devices, you might tolerate it, but I use a full-house setup with a router, phone, and laptop, all running WireGuard. With 50 Mbps download speeds, I consistently get 45+ Mbps, and since UDP directly traverses NAT, tunnel recovery is much faster than TCP.
For DNS, I switched the system DNS to AdGuard Home, with Unbound handling recursive resolution for AGH. This prevents DNS leaks while also caching locally for speed. On mobile devices, just import a single configuration profile, and you're good to go.
For split tunneling, I enable it on-demand: devices needing global access (like a Kindle) route through the tunnel, while others connect directly to the local network. This avoids issues with local printers, screen mirroring, or accessing my NAS at home.
I host the server on Japan AWS Lightsail (Tokyo), which offers low latency (similar to HK or SG for domestic players). I once tried GCP’s Seoul plan, but it had bizarre issues like "YouTube not working in Korea," so I recommend testing the route with Ping or mtr before committing.
One last tip from my own mistakes: manually check the "VPN sleep lock" settings on every device. After iOS 17, background connections default to dropping, so you must enable "Always Connect" in Settings → VPN → Auto-Connect. On Android, mark the VPN as "Not Optimizable" in the device manager to prevent the system from killing the process. On the router side, remember to whitelist port forwarding rules in the firewall—otherwise, every reboot or script refresh forces you to reconfigure the connection.
I've run into this exact problem myself when setting up a VPN for my home lab, my day-to-day laptop, my wife's phone, and my travel router. My first attempt was OpenVPN on a VPS in Frankfurt. It worked, sure, but every phone call or video stream was 3-4 seconds behind—constant buffering. Switched to WireGuard after reading some benchmarks, and the difference was night and day: upload tests jumped from 30 Mbps to around 80, and latency stayed under 20 ms.
I kept hitting DNS leaks when I forgot to set systemd-resolved to ignore the VPN’s DNS push. Fixed it by pushing the router’s own Quad9 DNS over DHCP, so everything—even the smart TV—routes through the tunnel. Split tunneling was a hard no after an HR login page flagged my presence in a country I wasn’t actually in—tunneling everything back home solved that mess.
For server placement, I tested a few regions: Frankfurt and Tokyo are great for speed, but Singapore’s jurisdiction scared me, so I landed on Amsterdam, where the provider is outside the 14 Eyes but close enough. Latency to Southeast Asia dropped by 30%, and I still get privacy when I need it.
