Lukas Hauser commented on ASTERISK-24687:
-----------------------------------------

You're right. Thank you so much.
I tried it with the 13.1 machine and it seems to work. (Can't test the 11.15 version right now)

{code}
;  c) Listen on the IPv4 wildcard.            Example: bindaddr=0.0.0.0
;  d) Listen on the IPv4 and IPv6 wildcards.  Example: bindaddr=::
...
; (Note that using bindaddr=:: will show only a single IPv6 socket in netstat.
;  IPv4 is supported at the same time using IPv4-mapped IPv6 addresses.)
{code}
I missed the last part, I though it would work with IPv4 addresses without mapping them.

Nevertheless, this is a strange behavior, isn't it?

> If asterisk is behind a statically configured NAT (e.g. with iptables), the externaddr or localnet option does not work.
> The Contact Header still contains the private IP address.
> The media_address option works.
> It also works as defined with version 11.7.0~dfsg-1ubuntu1.
> The Contact Header does not get updated in version 13.1 and 13.1.0-rc2.
> Therefore, I guess it is a bug in 13?
> Thanks!
