This site has previously shown us the method of segmenting a router into eight virtual routers using virtual Routing and forwarding (VRF, VM forwarding) through a scene example. I showed you how to configure VRF, and in this article we continue to use this scenario and, through IPSec configuration, replicate the exact topology and address to eight experimental environments. The entire environment can proceed smoothly, first requires the virtual route with ASA and Cisco router to establish

In order to reduce network costs as much as possible, while not affecting the needs of mobile office, a unit decided to install a VPN server in the local area network file server, so that the unit can trust employees anywhere through the VPN network connection, access to the unit file server important data content, And this access way security can also be guaranteed, is to kill both birds!

In March 1999, the Internet Task Force (IETF) published a RFC2547 by Cisco, describing a way for operators to provide virtual private network (VPN) services to users through an IP backbone network. This method uses an extended BGP (Boundary routing protocol) to distribute VPN routing information through the carrier backbone network, and uses Multiprotocol token switching (MPLS) to forward

Now there are still a lot of VPN Router applications, and the market demand is also very high, so I studied the VPN Router's questions about VPN multi-channel bundling, here I will share with you, I hope it will be useful to you. VPN (Virtual Private Network) technology is of great help and considerable economic signif

Virtual private Network (VPN) provides secure connections, but many problems may occur. The following are some situations and suggestions for handling them.The user cannot access the file server.If the user can access the file server through an IP address but not by name, the most likely cause is the domain name resolution problem. It may be due to a problem with NetBIOS or DNS host name resolution. If the client operating system uses NetBIOS, the
