Michael L. Young updated ASTERISK-20904:
----------------------------------------

    Attachment: asterisk-20904-nat-auto-and-rt-peers.diff

Mark, thanks for reviewing that last patch.  I was getting ready to post a review since it has been in use for a few months now without any issues.

In bringing the patch up to the latest revision and reviewing it one more time, I made two changes that I would like you to confirm that is correct.

If the "useglobal_nat" is turned on, currently we are only copying the SIP_NAT_FORCE_RPORT flag.  I think we need to also copy SIP_PAGE3_NAT_AUTO_RPORT as well.  Can you confirm if that is correct?  I have been testing this for the past week+ and haven't seen any problems occur do to adding this.

Attaching my latest patch which included changes to the other realtime schemas.

Thanks

> Issue is related to ASTERISK-20572, but appears to have been reintroduced in Asterisk 11.x.
> Bring up a realtime peer behind separated from the Asterisk server behind NAT.   When the peer is pruned and brought back up, the peer's external NAT address is replaced with the private IP from the contact header, if that address was present.
