Read a lot about using iptables to implement the port forwarding article, but I do not feel that the problem is very clear, now engage my own settings and use of the experience, to talk about its implementation process.
We have a computer, there are two network cards, eth0 network, IP for 1.2.3.4;eth1 even intranet, IP for 192.168.0.1. It is now necessary to forward the IP packets destined for the 81

As we all know, SSH is a secure transport protocol, which is more used in connecting servers. But in addition to this function, its tunnel forwarding function is more attractive.
If the two intranet between the Linux server need to log in with each other, or need to access a port in the intranet, worry that there is no public network IP, you can use the method has Ngrok (https://ngrok.co

Example of Port forwardingIf your program wants to do one thing at a time, multithreading is the quickest and most common way, but there is also a way to be particularly useful when I/O traffic is large. If your operating system supports the Select function, you can let I/O read and write in the background. This module sounds complicated, but there are actually many ways to understand i

Linux lower port forwarding is generally implemented using iptables, and using Iptables can easily forward TCP and UDP ports from the firewall to the internal host. However, if you need to forward traffic from a private address to a machine that is not on your current network, you can try another application-tier port redirector, rinetd. RINETD is short and effic

This article mainly introduces the example of port forwarding and redirection implemented by Python under the TCPIP protocol. it is demonstrated by a webpy site with two-way communication ports on the local machine. if you need a friend, refer to the following, we use webpy to write a simple website, listen to port 8080, and return the "Hello, EverET.org" page.
