Virtualization: Bridged, NAT, Host-only - Virtual machine connection types

3 modes of VM network connection: Bridged, NAT, & Host-only
Today my topic is how virtual machines communicate with the network.
Virtual machines can communicate with other virtual machines on the same host as well as other physical and virtual machines on the local area network. In order to do so, they need two virtual things: one is virtual NICs (vNICs); and two: Virtual Switches or virtual bridges.
There are basically three network connection modes when we set up virtual NIC : bridged connection; NAT; and Host-only.

I appreciate your work a lot. This is my ‘go to’ channel for anything that’s unclear. Half of the network related problems I had have been answered on this channel itself 👍🏻👍🏻👍🏻

[@PoeLemic]

Wow, this is an incredibly easy to understand video. I'd had some trouble with my VMs and their installation, but I think that I might have set it to NAT -- instead of Bridged. They were able to communicate, but not be seen from outside the Host. Honestly, I wish that I'd seen your video first, and not let the Manufacturers like VMWare convolute it so much.

[@adipcdc1737]

Thanks for yout video. I had a connection problem with bridged mode with a switch that has DHCP service I connected to a switch, with the following configuration, Dinamic ip on my laptop(host) and Dynamic ip on my virtual machine(windows 10). But the switch was going to fail. Dynamic ip settings cannot be used for the host and virtual machine in bridged Mode?.

[@narindermittal6772]

I am fond of your videos. Will it be possible for you to share the tools u use to create interactive videos

sure. animation is created by flash. Then I put everything together (text, voice, picture) with Corel Videostudio professional.

[@blessingbanda8749]

this is good stuff

[@j.h.6672]

If we take Virtual Box as an example, you actually explained the "NAT Network" with the port forwarding mode and not "NAT". By default, Virtual Box DHCP assigns one and the same virtual IP in the NAT mode to multiple machines that is 10.0.2.15 and they cannot communicate with each other.

[@sa9433]

waiting for his reply

[@Ahmedabbassi121]

tahnk you so much !

[@mohammadtowhidshirzad7118]

Thank you. that was a very good explanation. but the cloud around the topology kept distracting me so that I could not understand it completely.

[@20sGamerTamil]

to isolate the virtual machines we want to use host only network

[@adedejiemmanuel1]

If NAT resolves a public IP address to private IP address, where then would we need ARP? Please give me a scenario where these two protocols would be in use simultaneously?

[@snakekidsnakekid637]

When the physical host device receives the data from the physical network, how does it know which one of the virtual devices who requested it? Does it use PAT as its network address translation?

[@Mahesh-gq7fm]

Yes, PAT can be used. The network request can only be originated from the VMs as it is inside NAT network. When the host receives requests from VMs, it is stored in table with requested VM's IP, port, server IP, port. When the response from the server comes back to the host, it looks at the table entries made during the requests, it'll forward the response traffic back to the right VM
