asterisk users - Nov 2006 - How to change IAX default port 4569 to some other port

Hi all,

All of a sudden all my IAX DIDs have gone down. I couldn't find any reason
other than that the ISP is blocking port 4569. DIDs register fine from my
home server, but not from office server, which is not behind any NAT. SIP
registers fine. I am trying to change IAX port but it apparantly IAX works
only on 4569. Changing it in iax.conf doesn't do anything. Changing it is
registration string also doesn't help. How can I make IAX work on some other
port?

I think that the bindport setting in iax.conf is ignored on reload,  
you have to stop and start
asterisk for it to take effect.

If that doesn't do the trick, you will have to write some tricksy  
iptables port mapping rules
for 4569

Something like this should work in your iptables:

iptables -A PREROUTING -t nat -p tcp --dport 1234 -i eth0 -j DNAT
--to-destination 127.0.0.1:4569
iptables -I FORWARD 1 -d 127.0.0.1 -p tcp --dport 4569 -j ACCEPT

This would forward port 1234 to port 4569.
