Companies in China, Japan, the United States, Germany, Singapore and many other businesses have business, intermediary business Network with the company's proprietary GPN (Global Private Network Chinese name is the world's privatization networks) link, the current test to build a backup link for network redundancy and failover.The initial selection program is GRE over IPSEC, which runs the OSPF routing protocol.First, why to choose GRE over

Many people do not quite understand the meaning of configuring IPsec statements. The following describes the problem in detail. With the increasing popularity of Internet, the low cost of Internet access has prompted more and more enterprises to use VPN to achieve remote connection. Compared with traditional WAN connections such as leased lines, frame relay, and ATM, VPN not only has much lower cost, but also has no less security. Today we will mainly

Experiment content of Dynamic IPsec VPN in a star network: 1. Create a fully interconnected topology. 2. Take R1 as the center, so that R2 and R3 establish a neighbor relationship with R1 respectively, while the routes between R2 and R3 are not reachable. 3. Create a Dynamic IPsec VPN R1 # show run !!

In the previous article, the experimental environment was built. The protocol analysis can be performed once the IKE/IPSEC protocol is fully run and the relevant output and capture packets are collected. During the analysis, we will use the output of the IKE process and the Wireshark grab packet, combined with the relevant RFC, using Python to verify the calculation. First look at the full operation of the Protocol (filtering out irrelevant messages,

This document describes the IPSec configuration between the router and the Cisco firewall. The traffic between the headquarters and the branch office uses the private IP address, when the branch's local area network user accesses the Internet, needs to carry on the address conversion. Network topology Configuration Define the traffic to the router: Access-list IPSec permit IP 10.1.1.0 255.255.255.0 10.2.2.0

Hi folks, ??? As a result of a recent engagement looking at Windows Host hardening, I came Using SS this little trick and thought it might be useful at some point. The MICR Osoft IPSec filters used by window 2000 XP can be bypassed by choosing a sour Ce port of 88 (Kerberos ). First off, Microsoft themselves state that IPsec filters are not designed as a fUll featured host based firewall [1] and it is

I. Overview:IPSec VPN has a variety of methods through NAT, NAT-T is one of them. Generally, IPSec VPN cannot cross the NAT device because the ESP traffic does not have a port number as the TCP or UDP traffic does. When the first phase of the test of IPSec VPN is aggressive-mode, it is not intended to appear in the PIX/ASA by default if the NAT-T is not enabled, ipsec
