[asterisk-bugs] [JIRA] (ASTERISK-24687) Asterisk behind NAT sets wrong Contact Header

[Michael L. Young (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-24687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=224644#comment-224644 ] 

Michael L. Young commented on ASTERISK-24687:
---------------------------------------------

I do see a difference in the settings.  On the 11.7 machine, you are not binding to the ANY address, {{::}}.  It would appear you are binding to {{0.0.0.0}}.  Is that correct?

If so, can you try setting the {{udpbindaddr}} in sip.cfg in the 13.1 and this new 11.15 server to {{0.0.0.0}} instead of the ANY address and see if there is any difference?

> 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!
