Firewalls and Game Center

Firewalls have become a standard for most large networks, and often times you may even use one to protect your home computer devices.  The Wi-Fi networks you will likely be using your iPhone and iPad on will be behind a firewall, though this can actually be difficult for a few different functions and applications within your iPhone.  One of these is Game Center, the social networking center of your iOS gaming.  Here is a look at how to use Game Center when your Wi-Fi network is behind a firewall.

Firewalls will allow Internet use through ports, which are service-identification numbers.   There are a few ports set to be allowed through the firewall, but not too many so as not to compromise its security purpose.  The point here is that there are specific ports that are to be used along with Game Center so that it can go through.  If you are on a restricted Wi-Fi networks you must make sure that port forwarding has been adequately allowed for:


  • 443 (TCP)
  • 3478-3497 (UDP)
  • 4398 (UDP)
  • 5223 (TCP)
  • 16384-16387 (UDP)
  • 16393-16472 (UDP)


If you are, however, on a Wi-Fi network router that has a firewall and other security features that have the possibility to deny access, it is best to just talk to your network administrator and give the following port information to them.  The ability to actually configure ports is different depending on the system, software, and hardware the network is using.
