Use virtual machines to implement port forwarding and virtual machine port forwarding

Use virtual machines to implement port forwarding and virtual machine port forwarding

1. application scenarios

• Break through the Internet restrictions (for example, restrict access to external networks within the company, but open some ports, you can use some open ports to achieve port redirection)
• Remote Desktop redirection
• NC redirection to get Shell

2. experiment environment

• Virtualbox Virtual Machine
• Windows XP (as a firewall subnet client, Host-Only, ip: 1.1.1.10)
• Firewall (two virtual network cards, one connected to the physical network using the bridge, one using the Host-Only, ip: 1.1.1.1)
• Kali Linux (install rinetd as a traffic forwarding station, bridge network, ip: 192.168.43.164)
• Windows 2003 (as Server, bridging network, ip: 192.168.43.149)

3. Experiment Process

• Configure fire prevention policies

Enter the IP address http: // 1.1.1.1 In the XP browser to manage the firewall and set the firewall rule to only port 53 for communication.

• Install and configure rinetd on the card (use the rinetd command to manually enable rinetd before use, and pkill rientd to end the process at the end)

Installation command: apt-get install rinetd

Configuration: Open the configuration file/etc/rinetd. conf and find # bindadress bindport connectaddress connectport. Set these four parameters to use rinetd.

Bindadress: Bind Address (here refers to the address of kali)

Bindport: bind Port

Connectaddress: the address to which traffic is forwarded (windows 2003)

Connectport (forwarding to port 80 beyond the Internet restrictions, and Remote Desktop to port 3389)

　　　　

• Access

Enter http: // 192.168.43.164: 53 in the address bar of XP Liu Anqi to access the Windows 2003 page.

　　　　

• Remote Desktop Management

Run the mstsc command on the XP Terminal to open the Remote Desktop Management Tool and enter 192.168.43.164: 53.
