Working principle of VMware3 network modes (bridging, nat, and Host-only)Details on VMware network configuration 1: Introduction to three network modes after a virtual machine is installed, two NICs are added to the network connection: VMnet1 is the network interface in Host-only mode of the virtual machine, VMnet8 is a network interface in NAT mode. The following describes how to select a virtual machine n
VMware offers three modes of operation, which are bridged (bridging mode), NAT (network address translation mode), and host-only (host mode). To properly apply them in network management and maintenance, you should first look at these three modes of work.1.bridged (Bridging mode)In this mode, the VMware virtual operating system is like a separate host in the LAN, which can access any machine in the network.

Transferred from: http://network.51cto.com/art/201009/223440.htmThe use of DHCP and NAT is common in network protocols. Do you have some control over the two protocols? Here we have a specific introduction to these two aspects. First let's look at what DHCP is, what NAT is, and then compare the two.1. DHCPDHCP is an abbreviation for Dynamic host Configuration Protocol, which is divided into two parts: one i
1. NAT : A technology that transforms the IP address of the internal private network into the IP address of a legitimate public network, and solves the problem of insufficient IP address of the public network to some extent ;2. after NAT conversion, the intranet host can be established with the external network host for the next year and realize communication; The network user cannot know the IP address of
VMware is a well-known virtualization product company, and VMware ESXi is also a virtualization software designed for servers. On servers that install VMware ESXi, you can run multiple virtual systems at the same time to take advantage of server resources. One major feature is the ability to generate virtual network topologies that can manage traffic on different virtual systems by creating virtual switches, and also make the configuration of virtual devices more flexible. Unfortunately, VMWare

Brief introduction
As more and more families and small businesses acquire computers, they will find that the network is a very powerful tool for sharing computer resources. Internet connections are more valuable resources on the network and are likely to be shared. You need to deploy an Internet gateway for a shared Internet connection while taking advantage of inexpensive, simple, home or small office networks. Internet gateways typically use NAT (n
NAT configuration on a CISCO router is in full swing and causes the shortage of IP addresses. to alleviate this problem, an important application is NAT (Network Address Translation ), it is widely used. Through address translation, NAT enables enterprises to access the Internet by using only a small number of valid IP addresses on the internet, effectively allev

Introduction to load Balancing clusters
The software that realizes load Balancing cluster is: LVS, keepalived, Nginx, Haproxy and so on. The LVS belong to four layer (network OSI model), Nginx belongs to seven layer, haproxy can be considered as four layer, also can be used as seven layer.
The Keepalived load balancing function is actually the LVS

With the development of the routing industry, the market demand is more extensive, but many users still do not understand the routing configuration issues. Here we mainly provide a comprehensive description of the Cisco router NAT configuration. More and more INTERNET resource sharing methods are available. In most cases, ddnleased lines are widely used with their stable performance and good scalability.

I am eager for the first time to switch between vlan routing and nat addresses of Cisco switches. I am very energetic and have an undefeated spirit.

One of the VLANs goes through the-l
