Hi guys, The NAS maintainer was nice enough to get back to me, and problem has been sorted out. This is what was happening:
Their proxy servers are behind a load sharing device, which is why the retransmission of one of the records had a different client_ip_address, but both entries came from the same NAS-ip-address. I have removed the client_ip_address from the unique_id declaration, and made the unique_id column unique in my database, so this should solve all my problems :] Thanks so much for your time and help!
