Hi Simon, > Is your firewall redirecting incoming connections on n.n.n.n:5036 to > the Internal Asterisk instance? If you don't see any messages on the > inside Asterisk box it's unlikely. More than that... Asterisk is configured as DMZ in the NAT router, so it is fully exposed to the internet. More, from outside I can register a SIP phone to the internal Asterisk and use it for placing calls.

This is what I get on the internal PBX when trying to remotely connect using IAX protocol, by dialing extension 103. 16:17:29.382604 193.221.214.29.5036 > 192.168.33.99.5036: udp 121 (DF) [tos 0x10] 16:17:29.395536 192.168.33.99.5036 > 193.221.214.29.5036: udp 12 (DF) [tos 0x10] 16:17:29.396791 192.168.33.99.5036 > 193.221.214.29.5036: udp 30 (DF) [tos 0x10] 16:17:29.682915 193.221.214.29.5036 > 192.168.33.99.5036: udp 12 (DF) [tos 0x10] 192.168.33.99 is the PBX behind NAT 1933.221.214.29 is the PBX directly connected to the Internet so the packets goes to the right place, but then...nothing.
