Just recently installed PIAF Green on Amazon (thank you Ward).
Using TM3 plus some of my own security ;-)
Noticed occasional attempts to register non existent extensions and wondered where or how these were getting through the firewall.
Upon investigation, I can see that the iptables understandably has entries for private networks :-
On Amazon they use 172 addresses to create your own private network between other servers. Is this a potential source for the false registrations / hacks ?
As a safety issue, I have removed these private IP address ranges (left 127.0.0.0/8).

Code:
-A INPUT -s 10.0.0.0/8 -j ACCEPT
-A INPUT -s 127.0.0.0/8 -j ACCEPT
-A INPUT -s 172.16.0.0/12 -j ACCEPT
