H3C MSR 3016 and Cisco 5510 ipsec vpn connection preface: Book connected to the http://www.bkjia.com/net/201210/162034.html, a previous branch of a VPN (cisco5510) device is damaged, temporary find a backup VPN (H3C Msr3016 ), after the system is refreshed, set ipsec vpn. Fortunately, the CISCO5510 configuration was backed up and H3C msr 3016 was reconfigured according to the original configuration. Www.2ct

In the wider application of the Internet today, an important problem is the security of computer communication. As a network system administrator, a basic responsibility is to ensure that the data in the network transmission, can not be unauthorized access to, view or modify, in the middle of the same time to ensure that the data can be encrypted transmission. How do you do that? In the Win2K network, we can secure the network through IPSec. The full

When implementing a new link Load Balancing Project, users often use firewalls as their egress devices. If the user's organizational structure is distributed, it is often necessary to build a security tunnel to communicate with the headquarters or branches over the internet through ipsec vpn. In this case, the firewall is responsible for the maintenance of the ipsec vpn tunnel in addition to serving as the

Install Strongswan: an IPsec-based VPN tool on Linux IPsec is a standard that provides network layer security. It contains Authentication Header (AH) and security load encapsulation (ESP) components. AH provides the integrity of the package, and the ESP component provides the confidentiality of the package. IPsec ensures security at the network layer. Confident

Overview Internet Protocol Security is a suite of protocols that provides a wide range of information safety features. Individual users or organizations can use the IPSEC attribute to protect the traffic of all applications without any modification to the application itself. IPSEC uses authentication, integrity checking, and encryption to protect data traffic. Data security is provided at the IP layer of t

When I first came into contact with IPSec, I was wondering why I had to negotiate for two phases? Negotiate an Ike SA first, and then negotiate an IPSec SA Based on the ike sa. Isn't it good to negotiate IPSec SA in one step? However, in practice, it is not so efficient to negotiate IPSec SA directly. For example, a co

Microsoft recognizes that large organizations face increasingly severe challenges in enhancing their network perimeter security. As organizations grow and business relationships change, it is increasingly difficult to control physical access to networks. Customers, suppliers, and consultants may connect mobile devices to your network for legitimate business reasons. The emergence of wireless networks and wireless connection technology makes network access easier than before. The increase in conn

GRE over IPSEC route configuration r1 (0/0) --- r2 -- (1/1) r3 GRE over IPSEC first ipsec solves the problem that ipsec cannot transmit multicast traffic in gre, that is, you can run the Routing Protocol in ipsec, and the protocol is encrypted !! R1: crypto isakmp policy 10

Internet Key Exchange (IKE)Before the two IPSec computers exchange data, they must first establish an agreement called "Security Association ", both parties need to reach an agreement on how to protect information, exchange information, and other public security settings. More importantly, there must be a way for the two computers to securely exchange a set of keys, for use in their connections. See Figure 7.Figure 7 Internet Key ExchangeIKE (Internet

Internet Key Exchange (IKE)Before exchanging data between two IPSec computers, a convention must be established first, a convention called a "security association", in which both parties need to agree on how to protect the information, exchange information, and other common security settings, and more importantly, there must be a way for the two computers to securely exchange a set of keys. For use in their connections. See figure Seven. Figure VII, I

This document describes the IPSec configuration between the router and the Cisco firewall. The traffic between the headquarters and the branch office uses the private IP address, when the branch's local area network user accesses the Internet, needs to carry on the address conversion. Network topology Configuration Define the traffic to the router: Access-list IPSec permit IP 10.1.1.0 255.255.255.0 10.2

Another protocol for implementing vpn is ipsec. To be precise, ipsec is a framework composed of multiple protocols. Its implementation can be divided into the following four steps: 1. implement data stream filtering control (control by acl) 2. Security proposal (implementing the working mode, selecting the security protocol, verifying the algorithm, and selecting the consistency of the encryption algorithm
