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 10.2.2.0 255.255.255.0 !---traffic to the router does not address conversion Access-list Non

This article describes how to solve the inconsistency between AES encryption and other languages in Node. js. For example, if you need to communicate with C # and JAVA, refer Example 1: These days have been plagued by a problem. The AES encryption of Nodejs is inconsistent with that encrypted by Java and C. Of course, you cannot decrypt it. Tangle for a long time: Later, it was not enough. I read the source code, or else I had to continue to struggle. On the Internet, nodejs AES is usually impl

suitable for trading. » Free simulated account registration, no risk! Read the foreign exchange quotation Beginners may not understand the foreign currency offer. In fact, you only need to remember the two principles to solve the problem: 1) The first currency in the currency pair is the base currency; 2) the value of the base currency is always 1. The dollar is the main character in the foreign exchange market and generally serves as the base currency for quotation. In the "m

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: Intranet IP 10.1.1.0/24, extranet IP 202.102.1.5/24, Shanghai office network settings: Intranet IP 10.1.2.0/24, external network IP 202.102.1.6/24. The following configuration steps are performed on both sides of the router: I.

(multicast/broadcast) IP packets within the tunnel. Therefore, DMVPN supports running Dynamic Routing Protocols over IPSec and mGRE tunnels. It should be noted that NHRP must be configured as dynamic multicast ing. In this way, when the branch router registers the unicast ing address on the NHRP server (Central router, NHRP creates a multicast/broadcast (multicast/broadcast) ing for this branch router at the same time. Cisco dmvpn configuration instance: Configure r1 # sh ruhostname r1 on the H
