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 procee

. It is invisible to the source and destination, but only to point-to-point connections in the network path. Both parties do not care about any vrouters, switches, proxies, or other security gateways between the start and end points of the tunnel. A VPN can be used to provide a VPN when a tunnel is used in combination with data confidentiality. The encapsulated data packet is transmitted within the tunnel o

Lab requirements: 1. Build an environment based on the topology. The business trip staff use a real PC to bridge a router and connect to the ISP;2. Traveling staff can access VLAN2 on the Headquarters Intranet through PPTP and access the WEB server on the ISP;3. A IPSEC-VPN is required between the departments of the total score to securely transmit the traffic through the ISP, among which VLAN3 to VLAN4 req

Due to the company's network restrictions, a lot of information could not be found, so I decided to build a VPN over the wall, but the domestic VPN is really not flattering, stability is called a poor ~ A friend just recommended a foreign VPS host and checked it out. The node in Tokyo, Japan was very fast and he decided to start one. Based on the principle of self-help and rich clothes, after I built the De

IPSec (IP Security) is the most common protocol used to implement VPN functionality. VPN can be realized by the corresponding tunneling technology. There are two modes of IPSec: Tunnel mode and transport mode. IPSec is not a separate protocol, it gives a set of architecture

Many people ask me how to implement IPSec VPN technology, and I've done a case to show you how to configure a router-based IPSec VPN. Due to work needs, the company's Nanjing office and the Shanghai office to establish a VPN connection. Nanjing Office Network settings: Intr

Application introductionIPSec VPN can be used to establish a secure tunnel between two sites and is often used for network interconnection between enterprise headquarters and branches. This paper takes a company in Beijing headquarters and Guangzhou Branch need to build a security tunnel for example, introduces the use of TL-ER7520G to build IPSec VPN settings.No

Use G1 to establish an IPSec VPN tunnel, which is configured as an instance of this document. The first step: to build a good VPN physical connection environment Step two: Set the router ① IPSec Step three: Set the router ② IPSec Step Fourth: View Verify Connection Statu

A rough description of the network topology: Router 1 is a Router without a private IP address, currently, VPN technology is commonly used to resolve the connection between the headquarters and branches over the Internet to solve internal private addresses)Router 3 is the headquarters, and Router 4 is the branch.IP address planning:Router 1 FastEthernet0/0 200.1.1.1 FastEthernet0/1 100.1.1.1Router 3 FastEthernet0/0 192.168.1.254 FastEthernet0/1 100.1.

Today, we will demonstrate how the Juniper SRX Firewall runs ipsec vpn + OSPF with Cisco routers.

The IPSec VPN realizes the network expansion, the firewall realizes the control and the filtering to the network traffic, therefore has the influence to the IPSec VPN communication. The default ASA maintains a state session only for UDP/TCP traffic, and therefore discards the ESP traffic that is returned. There are tw

This document describes the configuration of subnet overlapping IPSec VPN for all fortigate devices. When you configure VPN interconnection, you need to use NAT for address translation if the subnets on both ends overlap but cannot change any one end of the network to allow VPN
