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
software can crack the wireless network security settings including WEP encryption, WPA encryption, MAC filtering, SSID hiding and so on, as long as it has enough time to crawl the communication signal. This may sound disappointing, so how do we make wireless networks safer?
Ensure that wireless access networks do not rely on technologies such as WEP to be as s
Solution to VPN connection failure in Win7 System
Now there are more and more users in the WIN7 system, and problems with the WIN7 system are also coming! Some users reported that the connection failed during vpn connection in Windows 7 and the error code 868 was prompted. What is the problem? How can this problem be solved? The following small series will provide you with two solutions, hoping to help you

Application Introduction
L2TP VPN PC to site mode can provide terminal access to the security tunnel of the Headquarters network. If you are on a business trip, you can connect to the Internet, use the terminal's own VPN client dial-up connection, and establish a secure tunnel for data transmission.
This article describes how to build a L2TP VPN
This site has previously shown us the method of segmenting a router into eight virtual routers using virtual Routing and forwarding (VRF, VM forwarding) through a scene example. I showed you how to configure VRF, and in this article we continue to use this scenario and, through IPSec configuration, replicate the exact topology and address to eight experimental environments. The entire environment can proceed smoothly, first requires the virtual route with ASA and Cisco router to establish
In order to reduce network costs as much as possible, while not affecting the needs of mobile office, a unit decided to install a VPN server in the local area network file server, so that the unit can trust employees anywhere through the VPN network connection, access to the unit file server important data content, And this access way security can also be guaranteed, is to kill both birds! Recently, the uni
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
At present, Edge Routers are widely used, and there are also many problems. So I studied the security of MPLS-based VPN technology in Edge Routers, I would like to share it with you here and hope it will be useful to you. If an enterprise deploys a Multi-Protocol Label exchange MPLS) managed Virtual Private Network VPN (VPN) service, it will not only get high-qua
This is certainly not the first article on "Quick Guide to building a VPN using Cisco devices, however, we still hope that this guide will become an all-in-one guide for users who use ASA 5505 devices to set up VPN and connect to the Internet.
The ASA itself has a setup wizard, but this wizard does not cover all aspects of work required by the user, and some steps are vague, making it difficult for the user
The demand for the soft route of sea spider in the soft route market is still very high, and its performance is also very good, maybe many people do not know how to use the soft route of sea spider through the vpn line, it does not matter, after reading this article, you must have gained a lot. I hope this article will teach you more things. I believe many of my eldest brothers have already learned and done well by Using

Application Introduction
IPSec VPN can be used to establish a secure tunnel between two sites, often used for network docking of Enterprise Headquarters and branch offices.

The first time I used VPN, I purchased puff VPN, But I encountered many problems in MAC configuration. The general steps are not mentioned. Please search for them on the Internet.
If the network still fails after the correct settings, use a Windows host for testing. If windows can be used but Mac and iPhone cannot, the MTU value may be too large.
Run the following command on the MACOs terminal:

It introduces the connection mode in a connectionless network, this reduces network complexity and is compatible with various mainstream network technologies, greatly reducing network costs while improving IP service performance, it ensures the service quality of network communication and the security of data transmission. The combination of multicast technology and mpls vpn technology will provide operators with an unprec
