Hello Eric,
You need to multihome Kamailio so that it is simultaneously present on
the external and internal interfaces:
listen=udp:external.ip:5060
listen=udp:internal.ip:5060
Then, you need to force requests forwarded to the Asterisk boxes to go
out the internal interface explicitly. Prior to t_relay(), set:
$fs = "udp:internal.ip:5060";
If you want Kamailio to stay in the call path for the entire duration of
the dialog, you'll also want to ensure Kamailio puts dual Record-Route
headers in place for the ingress and egress interface. The
'enable_double_rr' modparam to the 'rr' module will ensure this.

Hi
I have two boxes with internal and external interfaces. Each has Kamailio at
the public interface and asterisk on the internal one.
Making calls within a box is fine but would like to load balance using the
other asterisk box.
However using dispatcher I have noticed packets are not being routed from
Kamailo to the second asterisk.
Packets from Kamailo are originating from the external interface and sent to
the second asterisk box using private ip address. Off course this is not
routable. I have tried masquerading but no joy. Do I need to change kamailio
configuration?
I want to have a set of asterisk boxes behind Kamailio using dispatcher. I'm I
missing a trick?
Eric
