Hi  all,


I’m currently trying to migrate my opensips V1.11.5 to  V2.1.3.


My server has 3 interfaces:

eth0 with public IP

eth0:0 with public IP provide via a keepalived script

eth1 with a private IP


Opensips listen on IP of eth0:0 and on eth1




Since i migrate to V2.1.3, load balancer probing is UP and down. After checking traffic, i find for each gateway used by load balancer table, there is 2 SIP OPTIONS sent.

-          First is sent with source IP of eth0:0

-          Second is sent with source IP of eth1


Any idea ?
