You may experience one or more of the following when trying to play a online multiplayer game:
- You cannot join or host a game.
- You cannot hear a player or a player cannot hear you.
- It takes longer than usual to connect online.
- A warning is displayed that your NAT type is “Strict” or “Moderate” and that you need to open ports on your firewall to play the game.
The Ramapo network is a enterprise level network which accommodates thousands of users and devices. Certain online games are not designed to support enterprise level networks. Some gaming developers or studios have chosen to accommodate home networks for their online gaming. As a result, this prohibits a enterprise network like Ramapo’s to be incompatible with online multiplayer gaming.
What is NAT?
NAT or Network Address Translation is a network technology which allows multiple devices inside a private network to share a public IP address. To use the Internet, you must have a public IP address as that identifies who you are and where data will be sent to when it is requested. Ramapo uses NAT so that the thousands of devices on the private network can share a public IP address at any given time.
What are the three NAT types and what is supported at Ramapo?
- Open NAT (Type 1)
- A private internet connection between you and your peer without the use of a firewall. In gaming, this means your gaming console has the ability to connect to anyone’s games as well as being able to host games where other players can find you.
- Moderate NAT (Type 2)
- A shared internet connection that is behind a firewall where all ports are forwarded to the source host only. In gaming, you may be able to connect to other players but certain features will be unavailable.
- Strict NAT (Type 3)
- A shared network connection where the public IP address is shared between multiple devices behind a firewall. In gaming, this means you have limited connectivity to other players. Players who have Strict or Moderate NAT will not be able to join your gaming session.
Ramapo supports Strict NAT (Type 3).
Can Ramapo change the NAT Type so that I can play my game?
Typically, on a home network, you have full capability to change your NAT type. However, because of Ramapo’s enterprise level network, this is not possible. This would require every device on the Ramapo network to have it’s own publicly available IP address. Unfortunately, public IP addresses are in short supply and can be extremely costly. The unfortunate truth is the game developers need to accommodate more than home networks and have wider support for enterprise networks. Ramapo is not blocking anything related to your game. Rather, the gaming developers need to design their games so that this not an issue regardless of what type of network a user uses.
