[arm-allstar] Using an Apple AirPort Extreme router

[Glenn]

I just finished successfully setting up an Apple AirPort Extreme router to use with my Asterisk Allstar Raspi. 

Here is what I learned after spending hours trying to get ssh into the Raspi to work. There is an equivalent DMZ on the AirPort Extreme called Default host. I logged into the AirPort Extreme and typed in the IP address from checking with ifconfig wlan0 from the Raspi. I was using an old Mac Book Pro laptop with High Sierra OS. Every time I typed the IP address in as the Default Host on the AirPort Exteme and did an update. I would get an update error message and the Default host IP address would not change. I did some reading online and found a post stating to try using an iPad to make changes and update an AirPort Extreme. I tried using my iPhone and The Default Host IP address I typed in changed after a successful update using my iPhone. I have no idea why my Macbook Pro laptop did not work? I hope this may help someone else trying to use an AirPort Extreme router. I can now ssh into my Raspi inside and outside my local network!
