>Is it ok to forward packets with an invalid checksum ? This code >does not check... If we want to conform to RFC-1812 (the IPv4 router requirements RFC), then yes, the header checksum must be checked. I personally think that for "fast" forwarding, it is a waste of CPU cycles. The IP checksum will be checked by the next hop, or at worst, at the destination host. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
