[SR-Users] answer back from wrong IP / Interface

Hi Gents, We have a redirect server based on Kamailio (4.2.3). The server has multiple IPs, but Kamailio is bound to only one address: http://view.xscreenshot.com/9dfdf449a387bdc6f9a719eae3620416 *Sometimes* it answers back from a wrong IP address, here is the proof: http://view.xscreenshot.com/ac661d6b303eda6653b37be7cf65aa65 The interesting thing is that if I do: root@tralab-route-01:~# ip ro get 10.121.24.51 10.121.24.51 via 10.121.43.30 dev vlan486 src 10.121.43.17 cache ipid 0x05ad root@tralab-route-01:~# So the 10.121.43.17 IP is selected, but I *do* expect that Kamailio send back the answer from the same socket where it got the request. What could be the issue ? Why does it do that *sometimes* ? In the majority of the time it works well.. I am not sure why this happens... Thanks, Mitya
