I understand a concept I was missing, once record_route() is called I have to
do a
if(loose_route()){
route(x);
}
I was trying to route it again using is_uri_host_local() and lookup("location")
but is_uri_host_local() was failing because the domain name was replaced by
an IP address.
I will continue to read and practice to understand concepts I am still
missunderstanding.
thank you for your help

Right, in the "200 OK" request the Contact as the private IP address.
I register with a domain name so I guess the same domain name as to be set in
Contact so I was expecting :
- > Contact: <sip:[email protected]:33802;rinstance=8572c408a8cc28e3>.
should be replaced by :
- > Contact: <sip:[email protected]:33802;rinstance=8572c408a8cc28e3>.
I have fix_nated_contact(); both in ROUTE and in REPLY_ROUTE the make sure it
is always executed, I understand it correctly
1.6.1. fix_nated_contact : "Rewrites Contact HF to contain request's source
address:port"
In my case Opensips will need a domain name to find that the target is
registered localy, how should I handle this, register with an IP ?

HI Julian,
The ACK will be routed based on Route + RURI info. Route hdr made the
ACK to get to .201 and the RURI will continue to .71. The RURI from ACK
is taken from the Contact hdr of the 200 OK reply.
AMybe posting the whole stuff (INVITE+200 OK + ACK) will make things easier.
Regards,
Bogdan
