 This case is well-known as directed broadcasts.  FreeBSD might have
 it disabled on purpose.  See RFC 2644 aka BCP 34.
 
 Formerly there was a sysctl for enabling directed broadcasts,
 IPCTL_DIRECTEDBROADCAST aka "directed-broadcast", obtained from
 NetBSD -- see netinet/in.h rev. 1.11 and netinet/ip_input.c rev.
 1.26.  Its definition still is in netinet/in.h but unused.  It can
 be just re-introduced.  See NetBSD's netinet/ip_input.c for example,
 search for "ip_directedbcast".
 
 Apropos, did you test how the fastforward path would handle directed
 broadcasts?
