[OpenSIPS-Users] Userloc, Bin Interface, and Clusterer combo

[Bogdan-Andrei Iancu]

Hi Sammy,

The registration records are usually bound to an interface (the ip and 
port the registration was received) - that interface will be used all 
the time in the communication with the registered end point.

Now, when if server A receives the Registration on interface X, and this 
is replicated to server B, this server B may not have the X interface, 
but something else (an Y interface). So the registration record will 
loose some information (the interface it is bound to). This is the 
nature of the error message you see.
And yes, using the ip_nonlocal_bind options is the way to go.

Once replicated, the registration records are independent and they do 
not depend on the what is happening with the original node (where the 
registration was pushed from).
