Understanding NAT Types:
- Open NATs can connect to any of the three types. --> Probably the least common type
- Moderate can only connect to open and moderate. --> Probably the most common type
- Strict can ONLY connect to open.
Strict NATs are a difficult problem with peer-to-peer games. Since most people don't have open NATs, the player with a strict NAT won't be able to find many joinable games.
Another problem is that sometimes the ISP (Internet Service Provider) is also behind a NAT, which often means even if you have a direct connection to the internet (without a router/firewall), the ISP still acts as a strict NAT.
PC: Some security or firewall software may block access to required ports or certain types of traffic. Check your security software settings to ensure traffic on the following ports is allowed.
For PC Online games, the following ports must be forwarded:
- Ports 5795-5847 (UDP)
For LAN games, the host must have the following ports forwarded:
- Port 7777 (UDP)
- Port 14001 (UDP)
PS4: For information regarding Playstation Port Forwarding please visit: http://manuals.playstation.net/document/en/ps4/settings/nw_test.html
Xbox One: For information regarding Xbox Port Forwarding please visit: http://support.xbox.com/en-US/xbox-one/networking/nat-error-solution
If you need assistance with opening these ports, please contact your Internet Service Provider for more information.
Here are some additional tips that have helped many players improve their connectivity:
- Make sure your router's firmware is upgraded the latest version (very important).
- Unplug your router for 10 minutes and plug it back in. Some older routers degrade in performance over time until it is rebooted, similar to a PC.
- Disable any firewall or other network filtering for the game.
- Enable uPnP (universal plug and play) on your router.
- If you don't care about security, enable DMZ (de-militarized zone) on your router for your PC's address. This turns off all of your router's firewall features for that specific PC.
- Contact your ISP and ask them what your DNS setting should be.
If you are still having issues connecting to the online servers after trying the above steps, try connecting your broadband modem directly to the console or PC you are playing the game on. This can help determine if the issue is related directly to the router or another source.
