[OpenSER-Users] dual nic at single machine openser

I got some routing problem configuring two NICs at debian. Openser is listening all possible network interface. I've configured one for static global IP address and one for internal private IP address. The reason why I've configured like this is for maintenance and development purpose. The static global IP line is for the service and the private IP line is for monitoring and administrations. But when I try to connect to openser of static global IP address, it was failed to register. 1) My machine was using private IP address of same subnet of openser connected to our private network. 2) My machine is trying to connect openser of static global IP address. In case of configuring dual NICs on Openser machine, is there any routing problem ? So I restricted the openser only listening static global IP address then it allows connection and succeeds in registration.
