![]() In Wireshark, the time column in packet captures is typically displayed in a Unix timestamp format, which represents the number of seconds since the Unix epoch (Januat 00:00:00 UTC). This enables you to monitor and analyze the network traffic generated by the guest machine, including its interaction with the host machine. Analyze the captured packets to inspect the network communication between the guest machine and the external network, including any traffic involving the host machine's IP address (10.0.2.2).īy capturing network traffic in Wireshark with the appropriate network interface and using a capture filter that includes the IP address 10.0.2.2, you can focus on the communication between the guest machine and the host machine in a NAT environment. This can include accessing websites, sending/receiving emails, or running specific applications.Ĭapture and analyze traffic: Start the capture in Wireshark, allowing it to capture the network traffic on the selected interface. Generate traffic in the VM: Perform activities within the guest machine that generate the desired network traffic. This capture filter will capture network packets involving communication to or from the host machine (from the guest machine's perspective). ![]() For example, you can set a filter to capture traffic to or from the IP address 10.0.2.2: Set capture filter: Optionally, you can set a capture filter in Wireshark to focus on specific traffic of interest. Typically, this interface is associated with the NAT adapter in VirtualBox (e.g., "VirtualBox Host-Only Network" or "VMnet8"). ![]() It serves as a gateway IP address that represents the host from the guest's perspective.Ĭapturing traffic with Wireshark: To capture network traffic from the VM running in NAT mode using Wireshark, you need to select the appropriate network interface in Wireshark's capture options. Host-guest communication: The IP address 10.0.2.2 is automatically assigned to the host machine's virtual network interface within the guest machine. The host machine performs network address translation, allowing the guest machine to communicate with the outside world. 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. ![]()
