Using Windows 2003 to build and structure a VPN server (ii)

VPN between site and site

Experimental environment:

Xi ' an Lingyun high-Tech Co., Ltd. because of the rapid development of business, set up a branch in Guangzhou: In order to ensure the XI ' an corporation and Guangzhou branch network of normal communication, resource exchange and convenient management; Initially we took DDN data line to connect the resources exchange and centralized management of Xi ' an corporation and Guangzhou , but this is also more practical and safe, but the cost of DDN is a great expense; To solve the company's a series of conditions, we decided to adopt a VPN to achieve the normal communication between the two companies, so that not only solve the general manager's distress, but also increased the security of the network and the availability of resources.

We used to have a VPN based on layer three IPSec on a previous Cisco router, so are we able to implement a second tier of L2TP site to site VPN solutions based on Windows 2003? The answer is yes, so let's wait and see!!!

Experimental purposes:

Able to understand the working principle of VPN and some related concepts;

Can understand the basic configuration of the second layer (L2TP) protocol VPN;

Mastering the basic methods of the second layer (L2TP) VPN scheduling error;

Can let Xi ' an head office and Guangzhou branch can normal communication;
