Hi Guys,
Using Centos 6.7, kamailio 4.2 and Ucarp I am testing
multiple VIPs on the same server and having some issues.
I have ucarp running, with 1 Public and 1 Private VIP
defined, and both are pingable and failover in a cluster.
The Public is for Subscribers to Register with, and the
Private for Communication to the Asterisk media servers behind
it.
My problem is kamailio when started states its listening on
both the VIPS, however when I try and force_socket over the
Private IP address, it states
ERROR: <core> [forward.c:218]: get_out_socket(): no
socket found
Mar 1 20:04:35 bt1proxy1 /usr/sbin/kamailio[20372]: ERROR:
<core> [forward.c:220]: get_out_socket(): no
corresponding socket found for(udp:10.70.0.72:5080)
Mar 1 20:04:35 bt1proxy1 /usr/sbin/kamailio[20372]: ERROR:
tm [t_fwd.c:520]: prepare_new_uac(): ERROR: can't fwd to af 2,
proto 1 (no corresponding listening socket)
This is when listening on the VIP which is 10.70.0.75 and I
also look to force_socket out of this IP. It just doesnt
work, however if I use the physical interface on the server,
that being 10.70.0.70, it works fine and forwards requests on
the Private LAN.
I have added net.ipv4.ip_nonlocal_bind = 1 to sysctl.conf
as well but no joy.
If 1 VIP is defined I have no issue, its just with 2, has
anyone had this issue before ?
Any help would be great.
Many thanks
Jon
