commit fc604767613b6d2036cdc35b660bc39451040a47
("ipvs: changes for local real server") from 2.6.37
introduced DNAT support to local real server but the
IPv6 LOCAL_OUT handler ip_vs_local_reply6() is
registered incorrectly as IPv4 hook causing any outgoing
IPv4 traffic to be dropped depending on the IP header values.

Chris tracked down the problem to CONFIG_IP_VS_IPV6=y
