If by destination you intend the MAC (ethernet) address of your
router, those packets are using the router as its gateway which is
exactly how it is supposed to work.
If they have the IP address of the router that's odd but it might well
be that the router is acting as a proxy too (odd but not impossible)
If you send in a SMALL sample we might be able to tell you for sure.
