Author: eugen Date: Tue Apr 7 17:49:36 2020 New Revision: 359707 URL: https://svnweb.freebsd.org/changeset/base/359707 Log: MFC r357053 by markj: ng_nat: Pass IPv6 packets through. ng_nat implements NAT for IPv4 traffic only. When connected to an ng_ether node it erroneously handled IPv6 packets as well. This change is not sufficient: ng_nat does not do any validation of IP packets in this mode, even though they have not yet passed through ip_input().
