How to Fix Nat Network Issue in VirtualBox

Check VirtualBox Network Settings:

  • Go to the settings of your Kali virtual machine in VirtualBox. Under the

  • Network tab, ensure the adapter is attached to "NAT Network" (not just NAT).

  • Make sure the correct NAT Network is selected (it should match the one you've set up).

Verify NAT Network Configuration:

  • Open the VirtualBox Manager and go to FilePreferencesNetwork.

  • Select your NAT Network and click the edit icon. Confirm that the "Network Name" matches and "Enable Network" is checked.

  • Check if DHCP is enabled. If not, you may need to manually assign an IP address in Kali.

Update Network Configuration in Kali:

  • Open a terminal and run:

    sudo dhclient

    This command forces Kali to request an IP address from the NAT Network's DHCP server.

  • Check your current IP configuration with:

    ip a

  • Ensure you have a valid IP address (e.g., 10.x.x.x or 192.168.x.x).

Test Internet Connectivity:

  • Try pinging a public DNS like Google:

    ping 8.8.8.8

    If this works, the internet connection is fine, but there might be a DNS issue.

  • Check if /etc/resolv.conf contains valid nameserver entries (e.g., nameserver 8.8.8.8). If it's empty, add:

    sudo nano /etc/resolv.conf

    And insert:

    nameserver 8.8.8.8

    nameserver 1.1.1.1

Restart Network Services:

  • Restart the network manager in Kali:

    sudo systemctl restart NetworkManager
