The problem may lie in your router, your network interface card or its

tcpdump sees the packet as malformed before it enters the netfilter

interface ?
Yes, but it will take time to arrange. It's very strange that it only
occurs on that range if IP addresses, which are also very similar to
the 192.168.0.0/16 private address range. I wonder if this would
improve if I changed the address range used on the ADSL router -
firewall to, say, 172.20.1.0. If it's software/firmware in the router
or NIC that might avoid it.
It's perhaps not that strange. I had a similar problem a little while
ago -- the networks guy had a set of blacklisted addresses in the router
that was rather out of date. He blamed his predecessor :-)
