Hi Gents,

It turned out that it ran with a wrong config and it was bounded to 0.0.0.0.

In this case the source IP is based on the routing decision, I can reproduce it.

I think Kamailio should be smarter in this case.

Thanks anyway.

Cheers, Mitya

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:

*Sometimes* it answers back from a wrong IP address, here is the proof:

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
