    You will want to research the misc@openbsd.org mailing list archives for the (correct) details, but I believe
this is a known issue with ipf versions prior to 3.3.20.  Something to do with the TTL not being properly
decremented (or incremented?)  I'll leave that as an exercise for the interested reader.

PS:  This question would probably be better suited for misc.
