<DIV><FONT size=2 face=Arial>Hi Olle,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Thanks for getting back to me.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Kamailio seems to be receiving inbound sip udp
correctly on the virtual IP's - and is able to respond to that received
traffic.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The issue seems more to be related to the mhomed
mechanism where Kamailio tries to identify the correct interface to use for for
new outbound traffic.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I do not understand your references to sysctl - can
you provide any example?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Many Thanks,</FONT></DIV>

<DIV><FONT size=2 face=Arial>Hi,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I am trying to install a Kamailio
server in a HA configuration, with IP's for 3 attached networks.
I am using Keepalived/VRRP to manage the VIP's. I have tested v 4.1.6
and latest 4.2.2</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2><FONT face=Arial>I have 3 x listen entries, one for each

<DIV>On a Linux system, kamailio can not listen to an address not assigned to
the system, without a specific sysctl.</DIV>
<DIV>If the 3 virtual IPs are independently moving between the servers, and
you have fixed the sysctl (which I</DIV>
<DIV>can not remember right now) you will always have kamailio's that can't
reach the network since the address</DIV>
<DIV>is not there. You may want to start Kamailio that listens to one IP when
that IP is assigned by Keepalived.</DIV>
<DIV>Keepalived has scripts executed when an IP is assigned or lost on the
system.</DIV>
<DIV><BR></DIV>
<DIV>Hope this helps.</DIV>

<DIV><FONT size=2 face=Arial>I have dispatcher set up to load balance over
two seperate groups of Asterisk servers, one on each private network.

<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>When I ran the system, Kamailio/Dispatcher was

<DIV><FONT size=2 face=Arial>Now, this might not be a Kamailio issue, as
when I run the same config with 3 IP's, but NOT using
