Re: [Serusers] Ser fowards invite on wrong IP Address

If I have Ser listening on two IP addresses it will forward a Invite from the address it received it on and not from the address the target registered at. This will cause a Nat problem as there will be no binding for that combination. In the example below Stephen is registered at xxx 162 and 888 at xxx 163 and both are behind the same Nat. A call is attempted in each direction. Is this the correct behavior?
