1. Install vmware workstation. 2. Install the guest system. Here, I installed Red Hat Linux9. During the installation process, make sure that the network connection is in the NAT mode. Of course, you can modify it after installation. 3. Check all network connections in Windows XP. In addition to the original Nic, you should find that there are more vmnet1 and vmnet8. Vmnet1 is the hostonly interface, while vmnet8 is the NAT Network Interface we want to use. 4. Use ipconfig on the win

VM service providers may be attacked by hackers during operation. Common attacks include SYN and DDOS attacks. By changing the IP address, it is possible to find the attacked site to avoid the attack, but the service interruption takes a long time. A thorough solution is to add a hardware firewall. However, hardware firewalls are expensive. You can consider using the firewall function provided by the Linux
