/*
|
|
* 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.
