it apprears from tcp_output.c that the offset and length fields are in host order at the time that mforward is called, not the src, dst, port like I speculated above. in sys/netinet/ip_mroute.c, before you calculate the cksum, you need to use HTONS() or htons() to place these fields in network order. If you need a diff, I can give you one, I unfortunately cannot test it for you. --mark tinguely.
