In the network code will find that the program is applicable in the local area network, but between the external network and intranet and intranet and intranet is not feasible.The problem is NAT. First, the following NAT is introduced.Nat is the function of NAT (network address Translator), which is the translation of networks. As the name implies, it is a techno

Turn from: http://www.cnblogs.com/GO-NO-1/p/7241556.html 1, NAT (network address Translator) Introduction NAT has two broad categories, basic NAT and NAPT. 1.1. Basic NAT Static NAT: A public IP corresponding to an internal IP, one-to-one conversion Dynamic nat:n IP corres

The emergence of NAT technology stems from the requirements for private network security and the situation that IPv4 addresses are insufficient. Cisco IOS supports the following common NAT technologies. Today, I found that my colleagues in the company do not understand the implementation of Cisco NAT, which leads to configuration problems. Here we will briefly ex

Meaning of NAT traversal: Nat is designed to save IP addresses, but it hides the addresses of Intranet machines. "unexpected" plays a role in security. Invisible to the outside, non-transparent internal networks are also "fair" applications of the Internet, and the idea of "sharing" is not acceptable, especially the purpose of "Mutual Service" in P2P networks, therefore, traversing

First, we will introduce some basic concepts: NAT (Network Address Network Address Translation: Network Address Translation is generated when IP addresses are increasingly lacking. Its main purpose is to reuse addresses. Nat is divided into two categories: Basic Nat and Address/port translator ). Nat is a functional mo

The principle of NAT penetration technology today we will look at the NAT technology. When it comes to NAT technology, we may not be unfamiliar with it. It actually exists around us, but we seldom pay attention to it. NAT is a network address translation technique that changes an internal private IP address to a public

Conclusion 1: as long as one Nat is full cone Nat, bidirectional communication can be realized.Conclusion 2: as long as the nat on both sides are not classified as Nat, two-way communication is also possible. In other words, as long as the nat on both sides belong to the con

Any external host can send IP packets to the internal host through the ing. (2) Restricted Cone: Nat maps all requests from the same internal IP address and port to the same external IP address and port.

Linux-based NAT and firewall hybrid applications (very practical)-Linux Enterprise applications-Linux server application information, the following is a detailed description. 【Abstract] It mainly describes NAT (Network Address Translation) and NAT-based firewall technology in Linux. First, it is introduced by the installation of the Linux system. It focuses on th

What is punching and why? Due to the rapid development of the Internet, IPv4 addresses are insufficient, so each host cannot be assigned a public IP address, so Nat address translation is used. Below is a picture I found online Generally, a connection is actively initiated by a host in the private network (such as the "Computer A-01"), the packet is converted to the server on the public network (such as the "server "), after the connection is establi

As Internet technology continues to grow exponentially, the allocation of precious network addresses to private networks is finally seen as a waste of valuable virtual real estate. Therefore, the Network Address Translation (NAT) standard is used to leave some IP addresses for repeated use by the dedicated network. This article will show you in detail how to correctly apply the Network Address Translation NAT
