The progress bar sticks at eleven percent, then twelve, then stalls. The fourth time this week. Restarting the transfer doesn't help. Neither does switching wifi networks, or turning the whole router off and on like it's a stubborn toddler. Whatever's stopping my laptop from reaching my own setup isn't a speed problem — it's a travel VPN and port-forwarding problem, the unglamorous kind nobody mentions when they talk about remote-work security or streaming abroad.
Quick disclosure before I go further: some of the links on this page are affiliate ones, including Private Internet Access — sign up through them and I get a small commission, you don't pay anything extra. I only bring up tools I've actually paid for and lived with, because getting this wrong from a rented room three time zones from home is a genuinely annoying way to lose an evening.
This particular stall happened while I was based near Chiang Mai Old City for a stretch, trying to reach a setup I'd left running in the flat I rent in Lisbon's Graça neighbourhood — the closest thing I've had to a fixed base the last few years. A router that never gets switched off, a table permanently covered in laptops, a kitchen drawer that's turned into a small graveyard of spare adapters and old SIM cards. None of that helps if the network on the other end won't let anything back in.
Same PIA account, completely different job — I've written before about how the MACE ad-and-tracker blocking helps with ad-free streaming abroad, and none of that overlaps with what I'm about to get into here.
Why Port Forwarding Matters
Here's the short version, because I'm not a network engineer and don't intend to pretend otherwise: a lot of routers in rentals and hotels do something that keeps outside traffic from reaching back in at all, no matter how precisely you know what you're looking for. It's less a locked door than a building where none of the buzzers work — you can stand outside as long as you like, nobody's coming down to let you up. Port forwarding opens one specific, deliberate path through that for your own traffic, rather than hoping a hotel router will eventually cooperate.
My friend Bram, who's been drifting around the Bangkok-to-Chiang-Mai loop about as long as I have and writes backend code for a living, has opinions about this the way other people have opinions about football. Ask him anything remotely VPN-shaped and he'll tell you to split-tunnel everything — banking one way, streaming another, work traffic a third — even when, in my case, none of that complexity was actually the problem. Sometimes the fix is smaller than the theories people bring to it.
That's the toggle I finally switched on in Private Internet Access — once I'd stopped waiting for the Graça flat's router to have a change of heart.
I still keep NordVPN installed too (redundancy is basically a personality trait at this point) — it's not solving the same problem, but its ad and tracker blocking earns its keep on cafe wifi I don't fully trust.
For the fuller day-to-day picture, there's more in my Private Internet Access review for digital nomads dealing with latency — this piece is really just about the one feature that changed things for me.
The Easy Case: Streaming That Just Works
Streaming abroad is the problem people usually assume I mean when I bring up VPNs, and it's genuinely the simpler of the two. Before any of the port forwarding business, I'd ordered an Amazon Fire Stick from the UK store — preloaded with all the usual British apps — thinking I could just plug it into whatever hotel TV I ended up in front of. The first TV I tried it on had its HDMI port locked down entirely by the hotel: no override, no settings menu, just a dead port and a front desk that had clearly fielded this exact question before. That was the end of trying to solve a software problem with a piece of hardware.
What actually worked was almost embarrassingly ordinary. Sitting at a co-working desk in Mexico City one afternoon — more out of habit than any real hope — I opened the iPlayer homepage with the app just running quietly in the background, and it loaded. No region notice, no spinner, nothing to argue with, just the ordinary front page sitting there like it had never been a problem at all. That's the whole difference between the easy case and the hard one: for straightforward streaming, an app like ExpressVPN connects and gets out of your way, which is also why I've weighed in before on whether ExpressVPN holds up on Microsoft Teams calls, back when my partner needed it tested for work rather than for telly.
Reaching Into My Own Network Is the Harder One
This is the case nobody really writes about, because it's not about a show buffering — it's about needing to get something specific done from somewhere else entirely. A file server, a machine left running, anything sitting behind a router that isn't interested in visitors. Somewhere in the middle of sorting this out, I ended up tethered to my phone for an afternoon, feeding a captcha grid one tile at a time (crosswalks, traffic lights, the usual) while the connection tried to convince some server I wasn't a bot. That's the kind of friction port forwarding quietly sidesteps — your traffic isn't sharing an exit with however many other travellers used the same one an hour earlier.
The actual setup is almost anticlimactic once you get there. Inside the app it's a single toggle, and switching it on hands you a port number to drop into whatever's waiting on the other end — a remote desktop tool, a media server, a file transfer app, whatever the job needs. No engineer required, which is more than I can say for the three hours I once spent trying to explain 'port forwarding' to a landlord who seemed fairly sure I was asking him to summon something.
A friend from that same stretch in Lisbon, Reuben, asks the same question before trying anything new: does it lock you into a year you can't back out of. Fair question — and it's part of why the pricing side of this matters more than people admit. ExpressVPN doesn't do much for you if you only want a single month, while Private Internet Access gets noticeably better value once you're willing to commit for longer, which suits someone working out of one flat for years more than someone testing the water on a two-week trip.
Choosing Between the Two, Trip by Trip
So here's where I've actually landed, and it's less exciting than picking one hero app and calling it done. If all you want is your usual shows loading without a fight, a straightforward always-on app is the right tool — you'll be finished before you've even found the wifi password. If you need to reach something you actually own — a home setup, a file server, anything behind a router that isn't interested in guests — that's when the extra ten minutes with Private Internet Access and its port forwarding toggle earns its keep.
I keep both kinds of tool installed now, because I've stopped assuming any one trip only throws a single kind of problem at me. Some weeks it's just wanting the football on; other weeks it's genuinely needing to get back into my own stuff from somewhere with worse wifi than I'd like. Worth having the right one ready either way.
