AirPort Extreme won't open ports
I've been having trouble using some applications on my computer after switching to an AE and found that it's because the ports required to use them are not open.
I've already tried to make a rule, reset the router to factory settings and recreate my network 3x, but the AE refuses to open them. I am able to ping the servers that I would like to contact, however canyouseeme.org still tells me that the connection is being denied.
It is running version 7.7.3.
This is happening both on my computer and my roommates, so I know it's not an issue with my computer's firewall.
Any help/suggestions are much appreciated!
