Reading VirtualBox Network Settings Guide

Which network mode in VirtualBox can be used to emulate unplugging the Ethernet cable from the network?

The "Not Attached" mode

Which network mode would be best if you wanted to run a server on a VM that could be fully accessible from your physical local area network?

The Bridged Adapter Mode

What are the three options of promiscuous mode and what does each do?

1. Deny- traffic that isn't within the virtual adapter is hidden from the adapter
2. Allow Vms- the traffic that isn't hidden are all VM traffic. So VM to VM, but not outside of the virtual environment
3. Allow all- All outgoing and incoming traffic is visible to the virtual adapter.

What is Port Forwarding?

intercepting traffic to Ip Addresses and redirecting it to a different IP Address or port. The process of delivering the information by sending the message down the tube like in a mail room. For example, SSH is an example of port forwarding. By opening up port 22 and using it as a direct path to receive and send information. Or RDP, or HTTP port- opening up a port over the World Wide Web that will have an address that looks like this: http://10.10.10.72.8080. The 8080 is the Host port, the 80 the port they are using to access the World Wide Web
