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-network c

VPN has both public and private network features, the public network of reliable performance, rich functions and special network flexible, efficient combination.
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 business practices in the enterprise network infrastructure, every enterprise tries to underst
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.
