/*
 * Whats implemented:
 *  as_req_rsap(localaddr=0,localports=4-a:b:c:d,
 *              remaddr=0,remports=0)
 *  as_res_rsap(localaddr=24.128.34.21,localports=4-A:B:C:D,
 *              remaddr=0,remports=0)
 *  where a,b,c,d are listening ports on the client (192.168.0.2)
 *        and A,B,C,D are the associated ports visible
 *        on the external IP address 24.128.34.21.
 *
 * Operation: When packet from the outside is destined for
 *            24.128.34.21:A is recieved, the ip->dst and udp->dst
 *            (or tcp->dst) fields are changed to 192.168.0.2:a
 *            and then sent along - unencapsulated.
 *            When a packet is sent out from the client, the
 *            app (e.g. dplay) uses 192.168.0.2:a as in the
 *            IP+UDP/TCP header but uses 24.128.34.21:A for
 *            any information encoded in the data portion of
 *            the packet.
