This looks like a divert design issue.  IPPROTO_DIVERT is defined as an
alternative to IPPROTO_IPV4 and IPPROTO_IPV6, so only ip4 traffic is
received on the divert socket because there is no way to differentiate it
(ie "raw" ip4 packets are received w/o layer 2 header).

so, a FREEBSD kernel issue/ in the ipf4 module? divert subsection?


It is *BSD divert limitation.  I don't want to speculate on the module.
Maybe some others can clarify that.

This seems to be a long standing issue.  By now there must be a workaround.
Let me know.
