Comparison and Analysis of mpls vpn and VLAN + ACL
Scope of application: VLAN is essentially a LAN technology and is suitable for LAN isolation. However, VLAN alone cannot guarantee the isolation of IP services and must be used with ACL. In this way, all business systems are in the same IP address space, which is visible to each other and not truly isolated, leaving hidden risks for network security. Mpls
the contaminated ARP records are eliminated.
So far, you should be able to ping the other edge node with the vpn ip address from one edge node.Troubleshooting
The following error is returned when you call the edge daemon.N2n [4405]: ERROR: ioctl () [Operation not permitted] [-1]
Note that the edge daemon requires the superuser permission to create a TAP interface. Therefore, you must use the root permission for execution or set SUID for the

This digital certificate needs to be paid for purchase. It is relatively easy to set up SSL services for applications. If the application itself does not support SSL, you need to change some links, which are only related to the application. If there is a large amount of information, it is recommended to accelerate SSL to avoid traffic bot

Currently, VPN security technology is widely used. Here we mainly analyze the comprehensive application of VPN security technology on sites and clients. It is difficult to achieve network security, and the cost for achieving network security is very high. Due to the rapid development of commercial applications and busi
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
As we all know, due to the shortage of public IP addresses, we usually use reserved IP addresses as internal IP addresses when establishing a LAN. These reserved IP addresses cannot be routed over the Internet, therefore, normally, we cannot directly access hosts in the LAN through the Internet. To achieve this goal, we need to use VPN tunneling technology.-Generally, the VPN gateway adopts a dual-

It should be noted that prior to the use of GRE, you need to configure the physical interface as a VPN endpoint device, and then you can use security measures such as IPSec to protect the tunnel.

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.

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
Most enterprises need to protect internet communication. For many enterprises, the simplest way to protect communication is to use virtual private network (VPN) to create an encrypted channel between systems to communicate.
The most common use cases of VPN include connecting remote staff to the central data center, allowing them to securely access the internal re
