source ---> encapsulator --------> decapsulator ---> destination
The Router (decapsulator) will check the Protocol Type field in the IP 
header. If this is 4 (IP in IP encapsulation) then the Router will 
decapsulate the packet and forward it to the destination.
Is this the problem or you meant something else?

Regards,
Dionisios.
