When used `tcp_accept_haproxy=yes` and inbound connection from load-balancer received via IPv6 protocol and client real IPv4 then i can see error in the kamailio log ``` 28(723055) ERROR: {1 27 REGISTER 4fkReTbLC-} siptrace [siptrace_hep.c:94]: trace_send_hep3_duplicate(): interworking detected ? ```
Looks like requried add haproxy protocol support into siptrace module
Closed #3665 as completed.
The problem is that source address family is different than target address family, and HEP seems to have only one field for address family:
- https://github.com/kamailio/kamailio/blob/master/src/modules/siptrace/siptra... - https://github.com/kamailio/kamailio/blob/master/src/modules/siptrace/siptra...
So apparently you need to extend HEP and Homer Sipcature server, not only siptrace.
I am closing it as it looks not something easily to deal with, it is not only about Kamailio. If I am wrong, you can reopen, or just make a pull request with the changes.
