Hi Bill,

is your opensips actually listening (configured as listener in .cfg) on a interface in the private network (where the probing needs to be done) ??

Bogdan

Hey Bogdan,

I enabled the mhomed=1 parameter, and now I'm getting a bunch of errors in the logs.

ERROR:tm:t_uac: no socket found
ERROR:load_balancer:lb_do_probing: probing failed
ERROR:core:get_out_socket: no socket found
ERROR:tm:uri2sock: no corresponding socket for af 2

Thoughts?

Bill

Hi Bill,

as you have a multi interface system, have you tried to enable the
"mhomed" global parameter?

As an update, the load balancer probe appears to use the ip address
specified by the first listen= directive.

If I list the public IP first, then the probe tries to talk to the
internal IP from the external interface IP.

Hello everyone,

I've got an opensips-1.6.3-tls installation using multiple interfaces
and load balancing.

My internal interface  is rfc1918 space and my external interface has
public IPs.
listen=udp:10.0.10.3:5060
listen=udp:66.180.205.3:5060


I have the following load_balancer configuration:
  id | group_id |      dst_uri      | probe_mode
----+----------+-------------------+------------
   1 |        1 | sip:66.180.205.11 |          2
   2 |        1 | sip:66.180.205.12 |          2
   3 |        2 | sip:10.0.10.1     |          2
   4 |        2 | sip:10.0.10.2     |          2


What's happening is that the load balancer is trying to probe the public
IPs from the private interface IP (and failing of course).

tcpdump output on internal interface:
18:13:26.471734 IP 10.0.10.3.5060>  66.180.205.11.5060: SIP, length:
18:13:28.473802 IP 10.0.10.3.5060>  66.180.205.11.5060: SIP, length:


Thoughts?

Thanks,
Bill
