NAT networking in VirtualBox: In NAT mode, VirtualBox sets up a virtual network interface on the guest machine that allows it to access the external network using the host machine's network connection. Here's how it relates to capturing network traffic with Wireshark: When capturing network traffic of a virtual machine (VM) running in NAT mode with Wireshark, the IP address 10.0.2.2 is significant as it represents the host machine's IP address from the perspective of the guest machine. This information can be used to troubleshoot network problems, as well as to learn more about how the network works Wireshark can be used to view the contents of the packets, as well as the headers of the packets. Once you have captured the traffic, you can use Wireshark to analyze it. This filter will show all traffic that is sent to or from any IP address in the 10.0.2.0/24 subnet. You can also use the following filter to show all traffic that is sent to or from the VM:
This filter will only show traffic that is sent to or from the IP address 10.0.2.2. To filter the traffic to only show traffic from the VM, you can use the following filter: When you are finished capturing traffic, stop Wireshark and save the capture file. Start the VM and perform the actions that you want to capture traffic for. In Wireshark, filter the traffic to only show traffic from the VM. Start Wireshark and select the appropriate interface to capture traffic on.
To capture network traffic of a VM running in NAT mode with Wireshark, you will need to do the following: The IP address 10.0.2.2 is assigned to the host machine by VirtualBox and is used to communicate with the VM. This is because the NAT mode in VirtualBox uses a private network that is isolated from the rest of the network.
When capturing network traffic of a VM running in NAT mode with Wireshark, the IP address 10.0.2.2 will be used to represent the host machine.
