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 connectivity. It is not recommended to use overlapping addresses at both ends of the VPN. Environment Introduction: This article uses fortigate500a, fortigate310b to do the d

Use of the Scanner class(Accept keyboard input)Java.util.Scanner is a new feature of JAVA5, and the main function is to simplify text scanning. The most practical part of this class is to get console input, other features are very chicken, although the Java API documentation lists a number of API methods, but not very much."Code Sample"1 Public Static voidMain (string[] args) {2 test01 ();3 test02 ();4 }5 6 Public Static voidtest02 () {7Scan

Angry IP subnet obtains the IP address of the device. This software is used to scan the IP addresses of hosts in a certain CIDR block. Through usage discovery, the principle is to quickly ping each ip address. If a host exists, the user name, IP address, and Port of the host are obtained.For more information, see [Angry IP routing official website] (http://angryip.org/Purpose: use this method to retrieve the IP address of a network device.Scenario 2

A student asked me a question a few days ago, but I know little about the internet. So I asked my teacher, and I will get the answer today! IP :***.***.***.***Mask: 255.255.255.0It is divided into six subnets. How many computers can each subnet have? The answer is as follows: This question cannot be computed, because to divide subnets, it must be a power of 2 to n; otherwise, it cannot be divided. Some people say that this question is very diffic

Along with the gradual enlargement of the LAN scale, a network is divided into several different subnets, in order to realize the individualized management requirement according to the work requirements of different subnets. Considering that larger LANs typically use a DHCP server to assign IP addresses to each workstation, but once the LAN is divided into multiple subnets, do we have to create a DHCP server in each of the different subnets to provide IP address assignment services for workstati
