Is UPnP good for gaming? A gamer‘s perspective

As an avid gamer myself, I‘ve been using Universal Plug and Play (UPnP) technology for years to more easily connect with friends online and get the best multiplayer experience possible. While enabling UPnP does come with some security considerations, for most gamers the benefits far outweigh the risks as long as you take a few sensible precautions. In this article, I‘ll provide an in-depth look at how UPnP works, why it‘s so vital for modern multiplayer gaming, and how you can utilize it safely.

The growing importance of UPnP for gaming

First, let‘s quickly recap what UPnP does: it allows devices on a local network, like gaming PCs and consoles, to automatically discover each other and set up communication without manual configuration. It also handles port forwarding dynamically in the background rather than requiring you to input ports manually.

Over the past decade, UPnP has become more and more crucial for gamers as multiplayer and online connectivity have grown to dominate gaming. Back in the 1990s and early 2000s, many popular games were single player or supported local multiplayer only. But today, nearly every major title emphasizes online multiplayer features.

Popular franchises like Call of Duty, Overwatch, Destiny, Battlefield, League of Legends, and Counter-Strike center around connecting players together online. Even traditionally single-player series like Assassin‘s Creed now incorporate multiplayer elements. As a result, both game developers and players have come to depend on UPnP for enabling smooth multiplayer experiences.

According to a 2022 survey by Statista, 63% of gamers in the US play multiplayer games at least once a week, with this number steadily rising over time. The gaming industry‘s focus on online connectivity has made automatic port configuration via UPnP indispensable.

How UPnP simplifies multiplayer gaming

Without UPnP, playing games online would require significant frustrating manual effort. To allow incoming connections for multiplayer sessions, you‘d have to log into your router and forward ports manually based on your platform, game, and even gaming mode. This hands-on approach presents a few major headaches:

• You need advanced networking knowledge to forward ports correctly. The average gamer doesn‘t want to study up on managing router admin settings.

• Forwarding ports manually is different for every game and platform. Support sites might provide instructions, but it‘s still a hassle searching for the right guides and figuring out the correct configurations.

• Any time you switch games, you need to adjust your port forwarding rules. With UPnP, your router dynamically opens and closes ports as needed in the background instead.

• If you have multiple consoles or PCs gaming simultaneously, manual port forwarding simply won‘t work since it only allows one device per port. UPnP enables them all to connect.

By automatically handling port forwarding and device discovery, UPnP provides a seamless networking experience that just works. Gamers can spend more time actually playing with friends online rather than wrestling with technical networking hurdles.

How popular multiplayer games use UPnP

Nearly all of today‘s most popular multiplayer titles utilize UPnP to enable connectivity behind the scenes. For example:

• Call of Duty – Activision‘s official networking guide for Modern Warfare stresses the importance of enabling UPnP for the best multiplayer performance. The same applies across the CoD series.

• Destiny 2 – Bungie‘s shared-world shooter relies heavily on UPnP for fireteam matchmaking and multiplayer quests. Disabling UPnP often results in connectivity issues.

• Overwatch – Blizzard‘s team shooter grants players a "Double NAT detected" warning if UPnP isn‘t enabled, indicating problems for matchmaking.

• Battlefield – EA‘s technical troubleshooting for Battlefield 4 and Battlefield 1 both point to enabling UPnP to resolve multiplayer connection problems.

• Xbox Live – Microsoft‘s suite of multiplayer gaming services is designed specifically to leverage UPnP when available for online play between Xbox consoles.

And the list goes on – from massive multiplayer hits like Fortnite and PUBG to competitive esports staples like League of Legends and CS:GO. For today‘s social, connected games, UPnP is a basic requirement.

UPnP adoption across gaming platforms

UPnP capability is built directly into most modern gaming platforms and supported broadly across the industry.

Both major console makers, Microsoft and Sony, integrate UPnP into their latest systems. The Xbox Series X|S and PlayStation 5 consoles include UPnP clients to automatically configure optimal networking. Even Nintendo‘s Switch offers limited UPnP support.

For Windows PC gaming, UPnP server/client functionality is baked directly into Windows 10 and 11. And it‘s enabled by default in the most popular gaming digital distribution platforms like Steam, Origin, Uplay, and Battle.net to ensure multiplayer readiness.

On mobile, iOS and Android also include UPnP frameworks allowing games like Call of Duty Mobile and Pokémon UNITE to leverage dynamic connectivity. So virtually all major gaming platforms today either directly utilize UPnP or at least make configuring it easy for players.

Quantifying the rise of UPnP gaming

UPnP has essentially become an indispensable pillar of modern multiplayer gaming. Here are a few stats highlighting its ubiquitous adoption:

• Over 185 million PlayStation 4 consoles sold support UPnP out of the box.

• 90% of Steam‘s top 20 most-played games rely on UPnP for multiplayer.

• 63% of US gamers play multiplayer games at least weekly based on 2022 survey data.

• Xbox Live sees over 100 million monthly active users, nearly all leveraging UPnP.

• The Nintendo Switch has sold over 103 million units to date with basic UPnP capabilities.

• 71% of mobile games incorporate multiplayer functionality requiring UPnP.

As these numbers show, UPnP is firmly entrenched across platforms as multiplayer continues to thrive. For the vast majority of gamers today, enabling UPnP provides a seamless connectivity experience essentially required for online play.

UPnP security considerations

However, UPnP does come with potential security tradeoffs. Cybersecurity experts point out that while extremely convenient, UPnP introduces vulnerabilities that could be exploited by attackers.

The core risk stems from UPnP automatically opening ports on your router without your knowledge. If your router firmware is outdated or lacks proper firewall rules, this could potentially allow malware onto your network. Here are a few specific vulnerabilities that UPnP creates:

• Outdated router firmware – If security patches aren‘t applied, bugs could let malware manipulate UPnP to access your network. Always keep your router firmware up-to-date.

• Malware attacks – If one device gets infected, it could utilize UPnP to infect other local devices and gain more network access before you notice anything.

• DDoS attacks – By overwhelming your router via UPnP requests, criminals could potentially crash your network or devices with DDoS traffic.

• Firewall bypass – Without proper firewall rules, exploiting UPnP could punch holes through your router‘s security to gain entry.

These risks are real, but also quite manageable. By taking a few reasonable precautions, you can safely take advantage of UPnP for gaming while avoiding potential pitfalls.

Securing your network and safely using UPnP

Here are my top tips as a gamer myself for leveraging UPnP securely:

• Only enable UPnP while actively gaming, and disable it after you‘re done playing multiplayer. Leaving it on 24/7 is unnecessary exposure.

• Make absolutely sure your router firmware is updated frequently. Don‘t ignore those firmware notifications!

• Configure your router firewall to block unwanted incoming connections and detect anomalies.

• Run regular antivirus scans on all your gaming devices and PCs to detect malware early.

• Use a VPN for all your gaming devices to encrypt traffic and prevent snooping of any kind.

• If you don‘t play a lot of multiplayer games, consider leaving UPnP disabled entirely and just manually forwarding the few ports you need.

While no networking setup is 100% bulletproof, following this basic security hygiene keeps you pretty darn safe in my experience. For most gamers, the monumental multiplayer convenience UPnP delivers easily justifies taking a few precautions to secure it.

Weighing the pros and cons of UPnP

At the end of the day, enabling UPnP is mostly an easy choice for gamers to make connectivity painless. But let‘s quickly summarize the key pros and cons:

Only you can decide what balance of convenience vs. security makes sense for your gaming needs. But for most of us, the networking simplicity UPnP provides makes multiplayer gaming accessible and enjoyable.

The future of UPnP gaming

Looking ahead, UPnP will likely only grow more prevalent moving forward. As gaming gets more social and multiplayer-centric, automatic connectivity solutions become requirements, not luxuries.

And as emerging gaming platforms like cloud gaming and VR expand, they‘ll depend on UPnP scaling dynamically to enable their bandwidth-heavy experiences. We‘ll probably see UPnP evolve to become faster and more seamless over time as well.

But convenience often means more vulnerability. So we‘ll need to remain vigilant about pressuring device makers and game studios to bake robust security into UPnP implementations down the road. As gamers, we shouldn‘t have to choose between enjoyable experiences and safety.

My personal take as an avid gamer

As someone who‘s been gaming for over 20 years, I can‘t imagine juggling the multiplayer titles I play regularly without UPnP handling connections seamlessly for me. Maybe I‘m lazy, but I have zero interest in sorting out manual port assignments just to play Overwatch or Destiny with friends!

Have I ever noticed attacks or issues from leaving UPnP enabled? Occasionally over the years, but nothing seriously malicious. And those risks are easy enough for me to mitigate using basic security best practices. We have to keep the minor threats in perspective relative to how dramatically UPnP improves the gaming experience.

At the end of the day, I‘m grateful to have UPnP making my hobby more fun and accessible. It just takes a little attentiveness to enjoy it safely. But for most fellow gamers, it‘s a no-brainer networking helper that‘s essential for playing modern multiplayer games. I hope this overview gives you the info you need to make the right UPnP decision for your gaming needs!
