4 Reasons You Should Seriously Consider Turning Off UPnP on Your Router

In the early days of the internet, setting up home networks was a bit like trying to set up your grandmother’s old record player—complicated, with lots of wires and a bit of mystery. Each device had its own public IP address, which made things easy for game servers and file transfers. But it also exposed devices to the internet, and as we all know, nothing good comes from leaving your front door wide open. Enter Network Address Translation (NAT), which makes everything look like it’s on one IP address, keeping things a bit safer. But, of course, it was still too tricky to set up, so along came Universal Plug and Play (UPnP) to simplify things. Sounds like a dream, right? Well, not quite.

Here’s why you might want to turn UPnP off right now:

1. It’s a Security Nightmare

Sure, UPnP sounds great—auto-opening ports so your devices can talk to each other with zero input from you. But here’s the catch: No checks and balances. If UPnP is left enabled, anyone (read: hackers) can access your router and open ports without you even knowing. Think of it like leaving your front door wide open, but instead of a nosy neighbour, it’s a hacker wandering in. Yikes.

2. You’ve Lost Control

Imagine letting a valet park your car, but with no supervision. That’s what it’s like when UPnP is on. Devices can connect to sketchy servers without your permission, and once they’re in, they might even bring along malware. Some IoT devices and game consoles might seem innocent, but with UPnP enabled, there’s a risk they’ll invite trouble into your network. It’s a lot like leaving the keys in your car and hoping no one takes it for a joyride. Spoiler: They do.

3. It Makes Your Devices Perfect for Malware

UPnP doesn’t require authentication, making it a hacker’s best friend. Malicious software can easily use UPnP to open ports and create botnets (you don’t want to be a part of that). There’s a pretty infamous 2020 incident where millions of devices were roped into DDoS attacks because of vulnerabilities in UPnP. So, unless you want your smart fridge to turn into a hacker’s new favourite tool, it’s best to disable UPnP.

4. You Don’t Need It Anymore

Let’s be honest, you probably don’t need UPnP for modern gaming. Today’s consoles and gaming servers are way smarter. They use something called NAT punching to connect gamers without needing UPnP. Sure, you might run into the odd issue if you’re trying to play with a strict NAT type, but that’s a minor annoyance compared to leaving your network wide open for attack.

So, there you have it—UPnP may have been useful back in the day, but with the rise of smarter and safer alternatives, it’s time to say goodbye to this security risk. If turning it off messes with some of your devices, no worries—just manually forward the ports you need and keep the rest of your network safe.
