[OpenSIPS-Users] Unable to make the load balancer work

[M.Abdulaziz]

Hello Everyone,

I 'm  trying to run the load balancer module but I couldn't make it work
properly. I know it is due to my lack of experience. But I couldn't figure
out where is my mistake, can any one help please...I implemented it as
follows:



                                         
                                > Proxy1 >--->UAS1
UAC-->LoadBalancer>              
                                > Proxy2 >--->UAS2
                                
Where:

sipp(UAC):192.168.1.70:5062                    
opensips(Load Balancer):192.168.1.69:5060
opensips(Proxy1):192.168.1.69:5061
opensips(Proxy2):192.168.1.69:5062
sipp(UAS1):192.168.1.70:5060     
sipp(UAS1):192.168.1.70:5061   

I run the sipp command for the caller as follows:

sipp -sn uac -rsa   192.168.1.69:5060 192.168.1.70:5060

When I traced the packets using wireshark I saw the error message :

Destination unreachable (port unreachable)


The load Balancer table contains the following:

 ---- ----------- ----------------------------- ---------------------------- 
 |  id  | group_id | dst_uri                           | resources               
|
 ---- ----------- ----------------------------- ---------------------------- 
 |  1  |        1      | sip:192.168.1.69:5061    |  pstn=32               
|
 |  2  |        1      | sip:192.168.1.69:5062    |  pstn=32               
|
 ---- ----------- ----------------------------- ---------------------------- 


the load balancer configuration file is exactly as the one in the load
balancer tutorial(http://www.opensips.org/Resources/DocsTutLoadbalancing)
except the listen line:

listen=udp:xxx.xxx.xxx.xxx:5060

I changed it to

listen=udp:192.168.1.69:5060
 


Note: When I tried to send UAC calls directly to the proxy (e.g: sipp -sn
uac -rsa  192.168.1.69:5061 192.168.1.70:5060) without passing through the
load balancer it worked properly which means that my problem is in the load
balancer.

Best Regards,
