Allow Intranet machines to log on to MSN and QQ.(MSN and QQ are not allowed to log on by default) QQ can generally log on from TCP 80, 8000, 443, UDP 8000, 4000, while MSN can log on from TCP 1863, 443. The process of logging on to MSN and QQ is like accessing the Internet. It is also a designated port for accessing the remote server. Therefore, we only need to use data forwarding.-A prerouting-p tcp

Lan-based point-to-point voice communication

both parties have the ability to call the other party and receive the call from the other party. This only requires adding a listening socket. Once the call connection is established successfully, a data stream is established between the two points. Even if both parties do not speak, each point continuously receives and sends data, the voice of one Party naturally passes the data stream to the other party, so the key issue is how to read the voice data stream, because the stream service provide

In this example, we note that Nat uses different mappings from the same internal address and port A (192.168.0.4: 5000) to different destination addresses and ports, convert to different ports.The
