Along with the sixth great speed-up of China's railway, We are ushered in the advent of the power D era. The high-speed trains provide a fast way for our daily trips and greatly shorten the long journey time.
Similarly, VPN is an important "Railway" for commercial users to establish network connections ". One IPSec VPN is deployed in various regions, and users are connected in different region
Friends know how to configure VPN under win ' 2003, but many of these are based on the server in the public network IP premise, and at present many units are connected through a router outside the network, the rest of the servers are under the router, using the intranet IP, then how do we configure VPN? 51CCNP will be here to tell you a good way.

What is a VPN?
Virtual private network (VPN private network) refers to the technology of establishing a private network on a public network.
It is called a virtual network, the main reason is that the connection between any two nodes of the entire VPN

Introduction
A virtual private network enables the connection of components and resources across different networks. Virtual private networks can use the Internet or other public Internet infrastructure to create tunnels for users and provide the same security and functionality guarantees as private networks. (Figure 1)
A virtual private network allows a remote communication party, salesperson, or Enterprise branc
VPN (VirtualPrivateNetwork) is a virtual network established on the basis of the existing network, mainly used to help two networks communicate through the VPN tunnel. the advantage of VPN is that after the computer A1 in Network A is connected to the computer in Network B through A tunnel, A1 will be able to use the network environment of network B.
In March 1999, the Internet Task Force (IETF) published a RFC2547 by Cisco, describing a way for operators to provide virtual private network (VPN) services to users through an IP backbone network. This method uses an extended BGP (Boundary routing protocol) to distribute VPN routing information through the carrier backbone network, and uses Multiprotocol token switching (MPLS) to forward
As we all know, because VPN (Virtual Private Network) transmits private information, VPN users are concerned about data security. Currently, VPN uses four technologies to ensure security. These four technologies are Tunneling, Encryption and Decryption, and Key Management) user and device Authentication technology (Authentication ).

As a new VPN technology, ssl vpn gateway has its own unique characteristics and has its own merits. Ssl vpn is suitable for mobile users' remote access (Client-Site), while IPSec VPN has inherent advantages in Site-Site VPN connections. These two products will coexist in the
1. About VPN
(1) Virtual Private Network (VPN) is an extension of a private network. It contains Internet-like shared or public network connections. Through VPN, data can be sent between two computers through a shared or public network through a simulated point-to-point dedicated link.
(2) If it is more common, VPN is
To sum up, a VPN is a private connection that is established between two machines or two networks by sharing a public network. In fact, VPN technology enables organizations to safely extend network services over the Internet to remote users, branch offices, and cooperative companies. In other words, the VPN turned the internet into a dedicated WAN for impersonati
Network knowledge Review-VPN Virtual Private Network (VPN) refers to the technology for establishing a private Network on a public Network. It is called virtual network, mainly because the connection between any two nodes of the VPN network does not have the end-to-end physical link required by the traditional private network, but is built on the network platform
VPN we can understand it as a virtual out of the enterprise internal line. It can establish a proprietary communication line between two or more enterprise intranets that are connected to different places on the Internet through a special encrypted communication protocol. The virtual private networking function is to establish a private network on a public network for encrypted communication. VPN gateways e
It's not easy to install VPN client under FEDORA9
The data found that there are two ways to install, one is through the NETMANAGER-VPNC, the other is through the Pptpconfig
At first I was ready to pass the Pptpconfig way, but later found that pptpconfig can not be directly installed through Yum (online), if not through the Yum, you have to involve a lot of rpm, so give up, take the first line, because Netmanager in the F9 is ready-made, On the top o
Today, many SaaS and PAAs (Platform as a Service) vendors and developer fanatics have adopted cloud computing. In addition, some companies have expressed great interest in their virtualization projects, but have not yet formed a wave of implementation. It's not surprising, actually. Last year, cloud computing was not even in the top 10 list of Gartner's technology. Cohesiveft's CTO, Patrick Kerpan, says:
Security is a barrier to the implementation of enterprise cloud computing.
Despite the fac
Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we need to verify whether the RD function is implemented, whether the PE
Take a look at Vpn,vpn (virtual private network, VPN) is a secure, point-to-point connection through a private network or a public network. The VPN client uses a specific tunneling protocol to establish a virtual connection with the VPN server.

With the development of China's routing industry, it also promotes the constant update and upgrade of routing technology. Here we mainly introduce the performance and characteristics of Cisco VPN Router, with the development of the Internet, online Communication and transactions have become an important way for people to work. At the same time, network security also mentions the agenda of various enterprises.
In the face of the severe challenges of da
An example of Cisco Easy VPN comprehensive configuration is shown in this example. The topology is 15-15. In this example, the Cisco 831 router is used as the remote device of Easy VPN and the Cisco 1751 router is used as the device of Easy VPN Server. In this example, the WAN interface IP addresses of the Cisco 1751 router and the Cisco 831 router are both stati
With the rise of the wireless network age, vrouters must keep pace with the times and adapt to the application of new technologies. What features can a multi-WAN router make better use? The multi-Wan VPN Broadband Access Router is generated when the application needs it. In fact, the multi-Wan Broadband Access Router originated from advanced countries in Europe and America. Its main application is to help enterprises use bandwidth elastically, especia
