* 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. */#define RSIP_VERSION 1
