Well, probably not this. Still, just add a logging rule for INVALID
packets, just to check. I may miss something obvious, but for now, I do
not see anything but an INVALID state to cause this packet get dropped.

Also check if your conntrack table is not full (see
/proc/net/ip_conntrack file) and kernel log entries for some related
errors.
