This article provides a comprehensive explanation of LAN networking. During VPN networking for small and medium-sized enterprises, we will encounter many setup problems. Here we will introduce you to a configuration scheme for LAN formation, A diagram is provided to describe the Entire networking process in detail.
After setting up the Internet network on the Router, you can establish a VPN dial-up connecti
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.

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
"OK ".
You can now enable the server. The procedure is as follows:
1. on the PPP Main Window, select the Interface Tab.
2. Click the L2TP server button.
3. Select the enabled check box and click "OK ".
Now, you need to add an IPsec endpoint.The procedure is as follows:
1. Click IP> IPsec and select the Peer tab.
2. Click Plus.
3. Make sure that the Auth Method is a pre-shared key.
4. For Secret, enter a password as the pre-shared key. When configuring Windows, you can enter the password later.

Companies need to use a VPN server to meet the needs of the field Project department to connect to the company, so I used the WIN2003 server to do VPN services (no time to study 2008,2003 more familiar).
According to the previous Setup method, the VPN service was successfully set up, but when the field Project department was connected to the company, it was foun

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
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
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

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.

Virtual Private Network (VPN)
Virtual private networks are connected to a geographically different local network by means of the public network Internet, which is like local access. Because VPNs encrypt data as they transmit data, the security is high even though the data is transmitted over a public network. In the past few years with the VPN function of the hardware equipment is very happy to sell, some
Sometimes, because of the work or the software that wants to use the Cisco VPN client, there are often a variety of reporting errors in the WIN8 system, one of which is that the Cisco VPN Client reports a 442 error, and every time this report error is annoying, So how to deal with this report error! Now let's take a look!
The following is a specific error message:

This is a shame. When I implemented my VPN last year, I told the customer that our product was a two-layer device, so the customer was relieved because it would save a lot of maintenance time, because the L2 device does not need to configure network parameters, I think so, but he is wrong and
