Therefore, in the actual environment, it often corresponds to an IP address. When the SEC is used together, IPSec provides encryption of user data to provide users with better security. The GRE protocol has two main purposes: internal protocol encapsulation and private address encapsulation. In China, CEN uses almost all TCP/IP protocols,

DPD has become the standard built-in function in IKEv2. However, the Cisco IOS system by default this feature is dis

This is certainly not the first article on "Quick Guide to building a VPN using Cisco devices, however, we still hope that this guide will become an all-in-one guide for users who use ASA 5505 devices to set up VPN and connect to the Internet. The ASA itself has a setup wizard, but this wizard does not cover all aspects of work required by the user, and some step

There are many VPN products on the Cisco ASA Web VPN configuration market and their technologies are different. For example, in the traditional IPSec VPN, SSL allows the company to achieve more remote users to access the VPN in different locations, this service enables more

An example of Cisco Easy VPN comprehensive configuration is shown in this example. The topology is 15-15. In this example, the Cisco 831 router is used as the remote device of Easy VPN and the Cisco 1751 router is used as the device of Easy

Step 1 of Cisco ASA firewall VPN configuration: Create an address pool. To remotely access the client, you need to assign an IP address during logon. Therefore, we also need to create a DHCP address pool for these clients. However, if you have a DHCP server, you can also use a DHCP server. QUANMA-T (config) # ip local pool vpnpool 192.168.10.100-192.168.10.199 mask 255.255.255.0 Step 2: Create IKE Phase 1.

The VPN configuration of the Cisco router is not important for network security, but also makes the user more convenient during use. In this experiment, we use the Cisco 2600 router and the Cisco router VPN configuration to implement the blue campus. The networks between the

The firewall currently has a variety of models that provide different levels of interface density, failover capabilities, and VPN throughput.

This article uses VPN technology to achieve interconnection between two parts of the network, simulate ISP, close to practicality, the article mainly shows us the specific operation steps, mainly the input of basic commands. In this experiment, we use the Cisco 2600 router and VPN technology to achieve the network interconnection between one branch and two parts.
