customer, the ISP's pops must have the access server that allows the tunnel and the router that may be needed. The customer first enters the server by dialing. The server must be able to identify the connection.To establish a tunnel with a specific remote point, and then the server establishes a tunnel with the tunnel server, the user ID and password are usually used for authentication. In this way, the client establishes a direct conversation with the tunnel server through the tunnel. DoThis p

be more appropriate to use two NICs in situations where high availability or high performance is required. Eliminate the point of failure. It is necessary to use two NICs in an environment where high availability is required. A practical design is to include two switches in the core and two NICs per server. One NIC is connected to one switch and the other NIC is connected to another switch. What is the status of the internal network? For the same reason, internal networks should also be built

IPv6, as the foundation of next-generation networks, is widely recognized with its distinctive technical advantages. IPv6 not only solves the problem of IPv4 address depletion, but also improves the IPv6 Security Mechanism compared with IPv4. However, at the same time, IPv6 has higher requirements on hardware performance. 1. IPv6 Protocol Security In terms of Protocol Security, IPv6 Security mechanisms fully support authentication headers AH) authentication and encapsulation of Security effectiv

method is mainly used to add a non-transmission logic or implement a tunnel at a transport-dominated layer. For example, in pppoe, Ethernet is mainly used for LAN transmission, in addition, the price/performance ratio is reasonable, but the authentication mechanism is lacking. It is good, but it lacks multi-point communication and addressing capabilities. It is of little significance as a transmission protocol, so Ethernet is used for transmission and PPP is used for authentication, another exa

It combines several security technologies to form a complete system, which has received the attention and support of many vendors.

Currently, the method of connecting Internet users through a modem or a dedicated line is gradually replaced by a virtual private network (VPN). VPN allows users to communicate securely over the Internet. The conti solution provided by beidian network not only enables customers to establish various VPN types, but also integrates these VPNs into a network that combines voice and data in the future. In the opinion of beidian network, tomorrow's VPN will develop into a high-speed and secure network

I. Overview:A friend posted a post on the forum asking the ipsec vpn traffic of the two branches to pass through the headquarters. If the topology is set up, the test is performed because the performance of ASA8.42 running two VM versions is poor, therefore, the configuration of PIX8.0 instead of ASA should be similar to ASA8.0.Ii. Basic Ideas:A. the intercommunication traffic between the two branches uses the existing
