The following reply was made to PR kern/103950; it has been noted by GNATS. From: Yar Tikhiy <yar@comp.chem.msu.su> To: bug-followup@FreeBSD.org, damien.deville@netasq.com Cc: Subject: Re: kern/103950: [netinet] [patch] Broadcast packets are not forwarded Date: Wed, 11 Oct 2006 13:06:59 +0400 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? -- Yar
