I want to setup IP failover for Kamailio:
I have 2 hosts A (IP: X.X.X.32) and B (X.X.X.36), with 2 running kamailios.
Using Keepalive to setup IP failover as , virtual IP *is X.X.X.43*.
On host A, kamailio was binded to *listen=udp:0.0.0.0:5060
<http://0.0.0.0:5060>* and host A is MASTER with virtual IP
*Problem is:* Client send REGISTER to X.X.X.43:5060. It recieved 401
respond from X.X.X.32:5060 (actual IP of A), not as expected from
(To check if keepalived setting OK or not, I have *nc -l 5060* on host A,
and using nc X.X.X.43 5060 on client, wireshark show that responds is from
X.X.X.43 -> keepalived work OK
Is there any difference between *kamailio* and *nc* cause they both bind to
0.0.0.0, but repond on differ IP?
