What Is NAT Type? Open vs Moderate vs Strict NAT for Gaming

NAT type tells you how easily your console or PC can connect to other players online. For gaming, Open NAT is usually best, Moderate NAT is usable, and Strict NAT is the one that causes party chat failures, lobby errors, and those annoying “unable to join session” messages.

What Is NAT?

NAT stands for Network Address Translation. It is a router feature that lets multiple devices in your home share one public internet address. Your console, PC, phone, and smart TV each have a private local IP address, while your router talks to the wider internet using one public IP address.

That sounds boring, but it matters a lot for games. Many online games need to send traffic directly between players. Your router has to know which device should receive that traffic. If the router blocks or mishandles those connections, the game may still load, but multiplayer features can get messy.

This is why two players can have the same internet speed but get very different results. One joins matches instantly. The other keeps getting kicked from voice chat. It drives me crazy that a speed test can show 500 Mbps, yet a simple party invite still fails because the router is being too restrictive.

What Does NAT Type Mean for Gaming?

Your NAT type describes how open or restricted your network is to incoming gaming traffic. The exact labels vary by platform. Xbox commonly uses Open, Moderate, and Strict. PlayStation often shows Type 1, Type 2, and Type 3. Nintendo Switch also reports NAT ratings, often from A to F.

The idea is the same: does your system accept connections easily, or does your router block too much?

• Open NAT: best compatibility with other players.
• Moderate NAT: works most of the time, but some connections may fail.
• Strict NAT: most limited and most likely to cause multiplayer problems.

Open NAT: Best for Multiplayer

Open NAT means your gaming device can receive the connections it needs. Matchmaking tends to work smoothly. Voice chat is more reliable. Joining friends is easier. Hosting peer-based sessions is usually possible.

Open NAT does not mean your ping will magically drop from 80 ms to 20 ms. NAT type is not the same as latency. It is more about whether the connection can be created in the first place. Still, when connection attempts fail, games often retry in the background. That can make menus feel slower and lobbies feel broken.

For most players, Open NAT is the goal. It gives your console or PC the widest set of possible connections. If a game uses peer-to-peer networking, this can make a real difference.

Moderate NAT: Usually Fine, Sometimes Annoying

Moderate NAT is the middle ground. You can play online, join many matches, and chat with friends. But you may run into issues when connecting to players who also have restricted networks.

With Moderate NAT, you can often connect to Open NAT players. Trouble starts when multiple people in the party have Moderate or Strict NAT. The game may fail to pick a host. Voice chat may work for one friend but not another. Invites may show up, then time out.

Honestly, it feels like the most irritating NAT type because it works just often enough to make troubleshooting confusing. One night everything is fine. The next night, your friend cannot join your lobby even though nothing seems to have changed.

Strict NAT: The Problem Child

Strict NAT means your router is blocking many incoming connections. You may still connect to game servers, download updates, and browse the store. But direct player connections can fail often.

Strict NAT commonly causes:

• Failed party invites
• Broken or missing voice chat
• Longer matchmaking waits
• Errors when joining friends
• Difficulty hosting lobbies
• Random disconnects from peer-hosted sessions

If you mainly play games with dedicated servers, Strict NAT may be less obvious. Competitive shooters often rely on central servers for matches. Even then, party systems, chat, and custom lobbies may still suffer.

Open vs Moderate vs Strict NAT

Here is the simple version:

• Open NAT: connects to almost everyone. Best for hosting and party play.
• Moderate NAT: connects to many players, but not all. Can cause invite issues.
• Strict NAT: connects to fewer players. Often causes chat and lobby problems.

If you play solo matchmaking, Moderate NAT may be acceptable. If you regularly play with friends, Open NAT is worth fixing. If you have Strict NAT, expect to waste time on invite retries, router restarts, and “try joining me instead” experiments.

How to Check Your NAT Type

Most gaming systems show NAT status in network settings.

• Xbox: Settings > General > Network settings. Look for NAT Type.
• PlayStation: Settings > Network > Test Internet Connection. Check NAT Type.
• Nintendo Switch: System Settings > Internet > Test Connection. Check NAT rating.
• PC: Some games and Xbox app network tools report NAT status. Router settings can also help.

Run the test more than once if the result looks strange. Routers can behave differently after updates, power cuts, or ISP changes.

Common Causes of Strict or Moderate NAT

Several things can make NAT more restrictive than it needs to be:

• Double NAT: two routers are handling traffic, often from a modem router plus your own router.
• CGNAT: your internet provider shares one public IP address across many customers.
• UPnP is disabled: your console cannot ask the router to open ports automatically.
• Wrong port forwarding: ports are missing, duplicated, or pointed at the wrong device.
• Strict firewall settings: router security rules block game traffic.
• Wi Fi extenders or mesh issues: some setups create extra routing layers.

CGNAT is especially frustrating. You can change every setting at home and still stay stuck with Strict NAT. If your router’s WAN IP does not match the public IP shown by an IP lookup site, your ISP may be using CGNAT.

How to Improve Your NAT Type

Start with the easy fixes first. Do not jump straight into advanced router menus if a reboot or setting toggle can solve it.

1. Restart your router and console or PC. Simple, but it clears stale mappings.
2. Enable UPnP on your router if available. This lets games request the ports they need.
3. Use a wired Ethernet connection if possible. It will not directly change NAT, but it removes Wi Fi instability from the problem.
4. Check for double NAT. If you use a separate router with an ISP modem router, put one device into bridge mode.
5. Set a static local IP for your console or PC, then forward the required ports for your platform or game.
6. Ask your ISP about CGNAT. Request a public IPv4 address if they offer one.

Be careful with DMZ mode. It exposes one device more directly to the internet. Some players use it for consoles, but it is not a great idea for a normal PC. Port forwarding is usually safer and cleaner.

Does NAT Type Affect Ping or Speed?

Not directly. NAT type is about connection access. Ping is about travel time between you and the server or host. Download speed is about bandwidth. These are separate issues.

That said, a bad NAT setup can make games feel slower. Failed connection attempts can delay matchmaking. Party systems may keep retrying. Host selection may take longer. So while NAT may not raise your ping number, it can still hurt the multiplayer experience.

What NAT Type Should You Aim For?

Aim for Open NAT if you play online often. It gives you the fewest connection problems and the best chance of joining any friend, lobby, or voice chat session. Moderate NAT is acceptable for casual play, especially if your favorite games use dedicated servers. Strict NAT is worth fixing if you play with friends, host lobbies, or use party chat.

The best setup is simple: one router doing the routing, UPnP working properly, no CGNAT from the ISP, and a stable wired connection when possible. Get those right, and your games should stop fighting your network before the match even starts.
