Contribution from Naoki Nishihara from OKI for Issue 1806 (SIP LB can not forward when node is listening on 0.0.0.0)
Useful for a multi homed address, tries to reach a given load balancer from the list of ip addresses given in param
@param balancerAddr the load balancer to try to reach
@param info the list of node info from which we try to access the load balancer
@return the list stripped from the nodes not able to reach the load balancer
