IPv6 tunnel Communication TechnologyIPv6 is a new generation of Internet communication protocol with many features: new Header Format, large address space, effective and hierarchical address and routing architecture, built-in security, new communication Protocol Neighbor Discovery Protocol for IPv6 that interacts with neighboring nodes, scalability. As a network manager, it is necessary to enhance understanding of IPv6 and prepare for the full upgrade

To disable IPV6 tunnel in Windows 7, IPv6 tunnel encapsulates IPv6 packets in IPv4 packets so that IPv6 packets can communicate through IPv4 networks. For devices using tunnel technology, IPv6 datagram is encapsulated into IPv4 at the entrance of the tunnel. The source and destination addresses of IPv4 packets are the

The WebLogic Web application is deployed under the Windows Server 2008 R2 operating system and tested after deployment, finding that the address of the test page is using the address of the tunnel adapter, not the static IP address, and that the network is not in the IPv6 access, Therefore, the decision to disable the IPv6 and tunnel adapters is as follows: Disabling IPv6 is simple, go to Control Panel \ N

, especially access network devices, it is foreseeable that IPv4 and IPv6 will coexist for a long period of time. During the coexistence of the two, how to quickly transition the entire network to IPv6, especially the access network, has become the key to restricting the development of the next generation Internet. For IPv6 transition, many international technical solutions have been proposed [3]. These solutions are classified by technical ideology and can be divided into tunneling and translat

Vxlan Introduction VXLAN is the acronym for Virtual Extensible LANs, an extension of the VLAN, a very new tunnel technology, and a lot of applications in open vswitch. The Linux kernel upstream has just joined the Vxlan implementation. It has a good scalability compared to the GRE tunnel and solves many other problems. In quantitative terms, it extends the bit's VLAN tag

The monitoring system has made new breakthroughs in the wireless age, especially in China. Our country has a complex terrain and a vast territory. We want to monitor tunnels in such a complex environment, wired monitoring is always limited, so the birth of the wireless monitoring system has injected fresh blood into the monitoring system. In the Monitoring System Application of the tunneling industry, the solution represented by the current wireless monitoring system is more practical and effici

Tunnel can be seen as the simplest form of VPN. Its parameters are simple as long as the Tunnel Source and Tunnel Destination parameters are configured. The following is an example of the configuration method: The topology is as follows: Create a Tunnel between R1 and R2 R1: S1/0: 192.168.1.1 F0/0: 192.168.10.1 Loop0:

In actual work, we often encounter the requirement to connect two local area networks in different locations. The use of FreeBSD IPSec tunnel method can easily connect two local area networks, and has good security. Here's a case to tell how to connect two local area networks in this way. Assume the following network structure: The two FreeBSD machines are configured with firewalls of two subnets, and IPSec support is added to the kernel configura

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. ▲Configure ipv6 on RedHat 　　 ① Re-compile the kernel: The current version of redhat supports ipv6 (all later versions of kernel after 2.0.x support ipv6), but it is not compiled by default.

OpenVPN-ng: The application-layer tunnel for Mobile Life, And openvpn-ng Application LayerVPN makes people think that it is always a good thing and a way to escape from supervision. In fact, VPN has become the only synonym for escaping from supervision. You see, no matter what technology, IPSec, or WEB Proxy, as long as it is the technology that encrypts the original information, it can all be called VPN, so there is a so-called layer-2 VPN technology

Vpn Principle and Implementation-tunnel implementation theoretically reasonable ip over ssl needs some additional technical support before it can be used, you must try to re-encapsulate an ip data packet by ssl. This action cannot be performed in the original standard protocol stack. The standard protocol stack does not support two-way data flow, one of the solutions is to modify the Protocol Stack and implement a lightweight ssl protocol layer under

in 6to4,auto-tunnel and ISATAP, the tunnel does not have a destination address, and the destination address is determined based on the destination IPv6 address in the package. so these tunnels are triggered together, so most routing protocols other than BGP are not supported, because they establish neighbors based on the link-local address of the peer, which does not satisfy the condition of establishing a

For network communication that requires encryption, there are many options, such as various VPN: L2TP/IPSec VPN, PPTP, SSL The following is a simple point-to-point IPSec tunnel, which is so simple that it seems that the Internet is not very large... Maybe I am not quite right. L2TP and various VPN gateways have found a lot... In this way, you can set the IP security policy of the Local Machine to perform security negotiation for specific network commu

HTTP tunnel principle and firewall penetration method-1 TunnelMany articles are interpreted as "Tunnel" and "channel ". Tunnel is a communication method that bypasses the firewall port shielding, which can effectively shield the firewall from the port. Principle:Packets at both ends of the firewall are encapsulated on the data packet type or port allowed by the f
