It's possible that your NAT type or UPnP (Universal Plug and Play) settings may be preventing people from connecting to you.
If your NAT type is "3" and/or your UPnP status is "Unavailable", then you likely are having router issues that are blocking people from connecting to you.
Ideally, you want UPnP set to "Available" and your NAT setting at NAT 1 or NAT 2.
Please visit our support resource page for more information on how to diagnose and set your NAT Type!
