Re: [SR-Users] Transport issue thought

Thank you Alex and Federico, I verified, and SO_REUSEPORT is defined on my OS. I am using Kamailio 5.2 and I set ‘tcp_reuse_port=yes;’ and $fs; this has been to no avail as ‘ACK’s’ are still using the high port number randomly assigned by Kamailio. Thank you all for sharing your knowledge!

Kamailio's parameter tcp_reuse_port, if enabled and your OS has support for SO_REUSEPORT (so not only Linux but FreeBSD, OSX and others), allows you to use force_send_socket (or $fs) to send messages from a TCP port kamailio is listening to.

I believe Kamailio does the latter and does not offer options to constrain the range. If it does, I'm not aware of any apart from this one: https://www.kamailio.org/wiki/cookbooks/5.1.x/core#tcp_reuse_port Not sure if it would help in this case, you'd have to give it a try.
