Recently, I have seen many vpn things and found that many manufacturers are paying attention to the implementation of Dynamic IP address-based vpn for small and medium-sized enterprises. Of course, cisco is no exception. In its ios12.3 (4) T, it began to support dynamic Address Resolution of vpnpeer. Now, in CiscoIOS12.3 (4) T, VPNpee is created based on the DNS
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

Compared with the complex IPSec VPN, SSL realizes the information remote communication through the simple and Easy-to-use method. SSL VPN is available for any machine that installs the browser, because SSL is embedded in the
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.
