This is a well-known bug in netfilter, reported multiple times by
multiple users.

It manifests itself in several cases, one of them is what you've
found.

See my other emails in this mailinglist from this year for other
examples, - examples which clearly and obviously shows the buggy
behavior.  There are numerous other examples like this reported
over the years by multiple users.

Unfortunately, the netfilter devs don't consider it to be a bug.

Thanks,
