It is still difficult for general users to implement effective Cisco router nat configuration. So I have studied the comprehensive knowledge about Cisco router nat configuration and will share it with you here, I hope it will be u

Recently, a friend asked me how to configure static NAT for a Cisco router to allow Internet users to access the Intranet Web and email servers through a Cisco router. Obviously, this function requires NAT between the public IP ad
Experiment Name: Cisco router network address translation (NAT)Experimental purpose: To achieve all intranet IP to use a small number of public IP network connection to the InternetExperiment Introduction:With the help of NAT technology, when the intranet private address sends packets to the
CISCO Router Network Address Translation (NAT)Tutorial name: Cisco Router Network Address Translation (NAT) objective: to connect all Intranet IP addresses to the Internet using a small number of public IP addresses. Tutorial Intr
With the development of the routing industry, the market demand is more extensive, but many users still do not understand the routing configuration issues. Here we mainly provide a comprehensive description of the Cisco router NAT configuration. More and more INTERNET resource sharing methods are available. In most cases, ddnleased lines are widely used with thei
customized within a Network as needed without application. In the network, computers communicate through internal IP addresses. When the internal computer needs to communicate with the external internet, the device with the NAT Function (such as a router) converts an internal IP address to a valid IP address (that is, the requested IP address) for communication.

In Cisco router configurations, NAT configurations are frequently used. I hope the introduction below will be helpful to the majority of fans. It is a common method. The vro performs simple NAT translation and sets a CIDR Block in the NAT address pool. After a while, I found
NAT configuration on a CISCO router is in full swing and causes the shortage of IP addresses. to alleviate this problem, an important application is NAT (Network Address Translation ), it is widely used. Through address translation, NAT enables enterprises to access the Inte

Test ideas:A. Enable resolution by IP NAT without setting the direction---this way can be accessed directly from the public IP address, or can be accessed by domain name method---unfortunately Cisco is different iOS, so
NAT technology is a commonly used technology in the vro configuration process. How do I configure and implement its functions? How does it work? The following article will give you a detailed answer.
NAT (Network Address Translation) is the Translation of Network IP addresses. NAT is designed to address the increasing shortage of IP addresses. It maps multiple in

If the ISP provides many IP addresses, you can use NAT to map an external address to each server. However, if it is not the case (for example, if it is only two times), there are four servers in the Intranet that need to provide external services, one for Intran
Cisco router nat translation 1. One-to-one correspondence between the internal address and the egress address disadvantages: When the egress address resources are scarce, only a small number of hosts can be connected to the internet. 2. The internal address shares the egress address. The router uses the egress address
enable ip nat inside on the interface. In this way, the packet that enters from this interface performs route search first, then, query the NAT table. If the corresponding table item is found, perform the NAT operation.3. 1. Design of the conversion direction and switch point-Cisco NATThis section describes how to use

table to save the information of the session.
To really understand NAT, you must first understand the current IP address, the private IP address refers to the internal network or host IP address, the public IP address refers to the internet on the world's only IP address. NAT is implemented in the following three ways:
static address NAT:
Nat[network address translation] In the absence of IP address in the case of a great use, it can not be normal Sisu network of the intranet address into a legitimate external network address on the public network to send and receive data. At the same time address translation function can also be very good to hide and protect the host network.Nat has static NAT (internal address and external address one-to-o
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
