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

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

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

[CISCO] NAT configuration full guide vronat NAT Function configuration introduction with the rapid development of the internet, the shortage of IP addresses has become a very prominent problem. A variety of solutions have emerged to solve this problem. The following describes an effective method in the current network environment: address translation (

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 useful to you. 1. NAT introduction: NATNetwor

There are still many things worth learning about Cisco router configuration. Here we will mainly introduce the details about Cisco router configuration. How to configure NAT Network Address Translation) so that computers on the Internet can access their internal Web and email servers through their Cisco router configur

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 address and the Intranet IP address. The following are the specific implementation methods.

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 Introduction: using NAT technology, when an intra

. The internal local addresses 10.1.1.2, 10.1.1.3, and 10.1.1.4 use static address conversion. The valid internal addresses are respectively 192.1.1.2, 192.1.1.3, and 192.1.1.4. 　　 Vro2501 Configuration: 　　 Current configuration: 　　 Version 11.3: 　　 No service password-encryption 　　 Hostname 2501 　　 Ip nat inside source static 10.1.1.2 192.1.1.2 　　 Ip nat inside source static 10.1.1.3 192.1.1.3 　　 Ip

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 that the address pool was a waste of time. W

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 Internet by using only a small number of valid IP

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 their stable performance and good scalability. DD
