asterisk users - Oct 2005 - Asterisk on dynamic extrenal IP behind a nat router.

Is there no way to have asterisk determine its IP either via upnp or else 
resolve a dyndns hostname rather then having an entry in the config file?

You could use a modem/router with a DynDNS server in it, that would take
care of finding the Asterisk address from the outside.
On the Asterisk server you can can (I think by default it is anyway) tell it
to bind to all IP addresses.

For SIP you need to change the externip= variable and then "sip
reload". If you detect the ip change using a cron script (dyndns.org
has info on this), you can easily do this, I did it for months until I
finally got a fixed ip.
