VPN access network technology is still developing very rapidly. At the same time, it can be seen that the market demand is growing and users are also increasing. I believe that with the technological innovation, its development prospects will be even better, it will lead the rapid development of the communication industry. In recent years, Virtual Private Network VPN established on public networks has devel
1. Why does Cisco push the second-tier tunneling protocol, rather than the third-tier tunneling protocol?
Both options are available from Cisco. Cisco did not highlight that one. The second-tier tunneling protocol is primarily used to access VPN schemes, while the third-tier tunneling protocol provides VPN support for intranets and extranets. The third-tier tunneling protocol can also be used for some
1 Introduction
With the rapid development of public networks such as internet and the development trend of international economic integration, there is more and more demand for the transmission of information through network between enterprises. How to guarantee the safety and efficiency of communication at the lowest cost is an issue of great concern to enterprises. The popular solution is to use tunneling technology to establish secure virtual private networks, the virtual private network (
Requirements for VPNBecause the VPN is for the Enterprise User Service, relates to the enterprise normal operation, therefore the following from the user angle analysis to the VPN several requirements.VPN availability: That is, the established network can meet the requirements of the user's business. After the enterprise user's own business nature, the flow analysis, constructs one to adopt what technology
Recently found that a lot of friends in the search for free VPN account, through the free VPN proxy IP, using VPN technology to turn the wall to find what they want, pond, as a retreat and networking, today's Fast Cloud VPS Small series, to share, Use the relevant free VPN agent software and fast Cloud VPS How to confi
Now there are still a lot of VPN Router applications, and the market demand is also very high, so I studied the VPN Router's questions about VPN multi-channel bundling, here I will share with you, I hope it will be useful to you. VPN (Virtual Private Network) technology is of great help and considerable economic signif
Virtual private Network (VPN) provides secure connections, but many problems may occur. The following are some situations and suggestions for handling them.The user cannot access the file server.If the user can access the file server through an IP address but not by name, the most likely cause is the domain name resolution problem. It may be due to a problem with NetBIOS or DNS host name resolution. If the client operating system uses NetBIOS, the
Soft routing is an additional feature of PacketiX VPN.PacketiX VPN has always been used as a selling point as a professional VPN product. In addition to this function, PacketiX VPN can also be used as a soft route, this function is very similar to Microsoft's [Routing and Remote Access] function. It not only supports VPN
For remote Wan users, the virtual private network (VPN) should be a secure connection, but many enterprises question the security of VPN due to many obvious vulnerabilities. RainerEnders is the CTO of NCPengineering for VPN security in the Americas. In this article, we will learn how VPN security vulnerabilities are ge
First of all, lets talk about what is vpn I. e. virtual Private Network. basically it's a private network which lets users to connect to other users or remote sites using a public network usually Internet. a VPN uses "virtual" Connections routed through the Internet from the company's private network to the remote site or employee instead of physical connections. in short,

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.
a single network adapter configures the
VPN routing technology mainly uses tunneling technology and encryption methods. Here we mainly analyze how to use the VPN route table to use both the optical fiber access network and the telecom network. If you use IP address verification, and it is not suitable for normal ADSL and other dynamic IP address users, it is not convenient to use MAC address verification, because many ADSL uses a router to access
ADSL is called an asymmetric digital user line. ADSL is called asymmetric because its two duplex channels are used to transmit data to users, and only a small portion of bandwidth is used to send user information back. ADSL supports the upload speed of kbps on a copper-to-copper line ~ 1 Mbps, 1 Mbps ~ 8 Mbps, valid transmission distance between 3km ~ Within the range of 5km.Application of ADSLAdsl lan users have four fixed static IP addresses. enterprises applying for access through the adsl la
Application of SSL VPN
SSL VPN provides a variety of remote access services to the enterprise. Introduce the following common services:
E-mail: For enterprises, e-mail communication is a very basic function. IPSec VPN protects the messaging system, but IPSec VPNs need to install client software and connect to the corporate network before they can use an interna
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
ADSL is called asymmetric Digital subscriber line. ADSL is called asymmetric because its two duplex channels are used to transmit data to the user, only a small portion of the bandwidth used to send back to the user's information. ADSL on a pair of copper wire support upload rate 640kbps~1mbps, 1mbps~8mbps rate, effective transmission distance within the 3km~5km range.
The application of ADSL
ADSL LAN users with 4 fixed static IP address, the application of ADSL LAN form network units can be s
As a widely used access network method, the technology of the ADSL Router is very mature. Next we will give you a detailed analysis on how to perform VPN connection. 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 share
