I think the current terminology is correct FWIW. From a local network stack perspective for locally- sourced/destined packets, the source of incoming packets is the interface and the destination is a local socket. The source of an outgoing packet is the local socket (where it starts its journey) and the destination is the outgoing interface. More importantly, I would consider your proposed terminology inarguably backward for the case of forwarded packets. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
