[arm-allstar] Port forwarding

[Justin Reed]

Hello,

I just got my first Allstar Pi node up and running. In the near future 
I'd like to move this to a repeater site where it will live behind a 
router/NAT. What ports do I need (aside from my SSH port) to get 2 way 
audio working on this? I found a list on hamvoip.org but it looks like 
there are extra ports I may not need at this location.

Thanks,
Justin
