Sorry, there really isn't. What you can do is bind to an IP that is not currently bound to any network interface on the system, using the kernel "non-local bind" option. Then that listener will only take traffic once you bind the IP.
But that is only useful if you're dealing with a limited number of addresses which are known to you in advance. -- Alex -- Sent via mobile, please forgive typos and brevity. _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
