It was one of those humid evenings in Mexico City where the air feels like a damp wool blanket, and I was hunched over my laptop in a dimly lit Airbnb, staring at a 'Connection Timed Out' error for the twentieth time. I was trying to pull a massive design archive from my home server back in London, but the local network simply wasn't having it. This wasn't just a slow Wi-Fi problem; it was a wall I couldn't climb.
Before we go any further, just a quick heads-up: this site uses affiliate links. If you sign up for a VPN through these links, I earn a commission at no extra cost to you. I only recommend services like Private Internet Access because I’ve actually paid for them and used them to survive three years of digital nomad life across three continents. You can read my full transparency policy here if you’re into that sort of thing.
In the three years since I left London, bouncing between Lisbon, Bangkok, and Mexico City, I’ve learned that the 'security' of your connection isn't just about hiding your IP from hackers in a cafe. Sometimes, security means having a reliable, private bridge back to your own data that doesn't break every time a hotel router decides it doesn't like your traffic. That’s where Private Internet Access (PIA) and its port forwarding feature became my unlikely hero.
The Double-NAT Nightmare in Lisbon and Beyond
When I first started this remote contract in 2022, I thought a VPN was just a 'magic button' you pressed to watch telly. But after about six weeks of troubleshooting various connection drops in a flat in Porto, I realized that many rentals and hotels use something called Carrier-Grade NAT (CGNAT) or 'Double NAT.' Basically, it’s like trying to get a package delivered to an apartment building where none of the buzzers work and the front door is locked from the inside.
I remember spending three hours trying to explain 'port forwarding' to a Lisbon landlord in broken Portuguese. I was gesturing wildly at the router, saying "Porta? Não, internet!" while he looked at me like I was trying to summon a demon. I eventually realized that I didn't need him to change the router settings if my VPN could just handle the routing for me. Most VPNs don't offer port forwarding because it's 'too technical,' but for someone trying to access a secure home server or run a specific application while traveling, it's the only way to bypass those restrictive firewalls.

It’s another one of those 'set it and forget it' features that makes life on the road slightly less irritating.
University Challenge and the Mid-February Breakthrough
Mid-February in Mexico City found me in a particularly difficult spot. My partner does video calls all day for a production house, and they notice immediately when the streaming gets weird. We were sharing a connection that was already struggling, and I was desperate to catch up on the latest series of University Challenge. There are usually 37 episodes per series, and I refuse to miss a single 'starter for ten' just because our Airbnb router is being temperamental.
I was sitting there, squinting at the HDMI ports in the dark, feeling the sticky, tacky residue of a 'Property of Hotel' sticker on a remote control I’d somehow inherited from a previous stay. The stream kept buffering at the exact moment Amol Rajan was about to ask a question. I had this internal monologue going: If he asks a starter for ten and this stream buffers now, I am honestly going to throw this travel router out of the window.
That was when I finally sat down and configured the port forwarding on my Private Internet Access app. By opening a specific path for my media traffic, I wasn't just 'unblocking' content; I was creating a stable, dedicated lane for my data that the hotel’s firewall couldn't throttle as easily. It’s like having a VIP pass to the front of a very long, very annoying queue.
Why Granular Control Matters for Security
A lot of people will tell you to just use NordVPN because it’s easy, and for most things, it is. I even use it as my backup because it's great for public Wi-Fi. But when I need to get into the weeds of my network settings to ensure my design archives are syncing securely over AES-256 encryption, I find myself going back to PIA. It’s highly customizable, which can be a bit 'busy' for some, but for me, it’s the difference between a working day and a day spent yelling at a router.
The turning point was late one Sunday night. I had successfully routed a secure tunnel for my design software. My partner was in the other room, and I heard a visible exhale of relief as the 'reconnecting' spinner on their Zoom call finally vanished. I had adjusted the VPN tunnel settings to ensure their work traffic and my University Challenge stream weren't fighting for the same scrap of bandwidth. We were both using the same account, too, since PIA offers unlimited simultaneous device connections—a lifesaver when you travel with two laptops, two phones, a tablet, and a Fire Stick.
For a deeper look at how this handles the 'nomad life' specifically, you can read my Private Internet Access Review for Digital Nomads Needing Low Latency. It goes into the nitty-gritty of why speed isn't the only thing that matters when you're working from a cafe in Chiang Mai.
The Practical Side of Port Forwarding
You don't need to be a network engineer to use this. In the PIA app, it’s literally a checkbox. Once it's on, the app gives you a port number, and you plug that into whatever software you're using—whether it's a remote desktop app, a media server, or a secure file transfer protocol. It bypasses that 'Double NAT' nightmare that plagues almost every Airbnb I've stayed in from Lisbon to Bangkok.
I’ve tried other services, of course. I’ve had moments where ExpressVPN was my go-to for its simplicity, especially when I just wanted to see if ExpressVPN is good for Microsoft Teams calls during a particularly hectic week. But for the heavy lifting of travel security—the kind that requires you to actually reach into your home network from a foreign one—PIA’s port forwarding is the tool I keep coming back to.
Final Thoughts from a Professional Nomad
After three years of this, I’ve realized that travel security isn't a one-size-fits-all thing. Sometimes security is about privacy; sometimes it's about accessibility. Being able to maintain a stable digital bridge to my life in London while I’m sitting in a humid apartment in Bangkok is what keeps me sane. It’s the reason I can keep my job and my hobbies (and my sanity during University Challenge) intact.
If you’re tired of fighting with restrictive hotel Wi-Fi and just want your tools to work the way they’re supposed to, I’d honestly give Private Internet Access a look. It might take ten minutes longer to set up than the 'one-click' alternatives, but when you’re three months into a trip and your connection finally feels solid, you’ll be glad you have the extra control. It’s certainly saved me from throwing more than one travel router out of a window.
