[SR-Users] Unable to route outbound with multiple VRRP IP's

[mark at brightvoip.co.uk]

Hi,

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

I have 3 x listen entries, one for each network and mhomed=1.  Also, for info, we have net.ipv4.ip_nonlocal_bind = 1  in sysctl.conf

listen=udp:my.public.net.46:5060
listen=udp:192.168.106.46:5060
listen=udp:192.168.116.46:5060
mhomed=1

I have dispatcher set up to load balance over two seperate groups of Asterisk servers, one on each private network.  Dispatcher does probing to know which Asterisks are 'alive'.

When I ran the system, Kamailio/Dispatcher was not able to send any probing OPTIONS to any Asterisk (normal PINGS work fine in all networks in/out of Asterisk/Kamailio)

Looking at the log, I see these entries for all 3 networks:
Feb 12 17:28:19 app-srv-dev-1-01 /usr/local/sbin/kamailio[2992]: ERROR: <core> [forward.c:218]: get_out_socket(): no socket found

16.38:5060]

I notice from other logging that Kamailio is receiving and processing incoming OPTIONS messages, and sending appropriate replies.

Now, this might not be a Kamailio issue, as when I run the same config with 3 IP's, but NOT using VRRP/Keepalived/Aliased IP's, everything works normally.

However, I do need to run this setup in HA, so would welcome any suggestions as to how I might resolve this issue.

Kind regards,
Mark Hall
