Can I tell Virtualbox to use one of my ethernet cards? - networking

I have a laptop with the standard wireless and wired cards, I would like the host system to use the wireless connection and the vm machine to use the wired connection.
The point is that at the wired connection I can get a public, routable IP address, and I need that for my vm, while the host can work with the private IP.

You can assign any of your network cards detected by virtualbox to 1 of the 4 network cards you can put in the vm. See this for different modes

Set up a Direct Network between Host and Guest VMWare

I have a Soft PLC running inside a VMWare environment (Guest - Windows 8).
I want to connect to it from the Host (Windows 10) using the internal connections without having to set up a physical network switch.
My understanding of the documentation states that this should be achieved by Host only networking
https://docs.vmware.com/en/VMware-Workstation-Player-for-Windows/15.0/com.vmware.player.win.using.doc/GUID-93BDF7F1-D2E4-42CE-80EA-4E305337D2FC.html
And I've my PC Set up as:
The Network card in the Guest is set up as 192.168.0.244
On the Host, the network VMNet1 (Should be the DHCP Server) is Dynamic (DHCP) and resolved to 192.168.67.1 and VMNet8 (Should be the connection to the Guest) is also DHCP and has resolved to 192.169.73.1
All subnet masks are at 255.255.255.0 (DHCP defined?)
Even if I assign VMNet8 or VMNet1 to physical IP at 192.169.0.1 or 192.169.0.244 or 192.169.0.1 or even 192.168.0.12, I cannot ping the network card inside the host.
Am I missing something here with my setup? What am i doing wrong or has anyone got a step by step process for setting up a direct network connection between the Guest and host for testing communications without an external switch?
(I've disabled teh network connections between each setting change)
Found the issue.
The VM should have been set to NAT
The Network address of the adapter Inside the Guest set to the IP address I'm looking for
On my Host - VMNet 1 left alone as this is the DHCP Server
And set the VMNet 8 (Bridged connection between Guest and Host) to an IP address within a range of the subnet
And after disabling and re-enabling the connections, I can ping the PLC (192.168.0.1) running in simulation on the Guest from outside in the Host.
(Allows me to test node-red on the host connecting via OPC to PLCSim Advanced running on the Guest).

port forwarding to a virtual machine using Virtualbox

I want to forward a port to a VM. However i dont want the VM to be behind my host PC, i want it to be connected directly to the router so that packets coming on that port go directly to the VM without passing through my host PC.
In other words, i want the VM to look like any other machine on the network.
EDIT: i used bridged adapter, but i couldnt make it connect to the network.
Thank you
The VM will use the Ethernet port in all cases and the OS in it.
Typically if you have Windows and a VM with a bridged port, you will see the traffic flow when you take a capture on the Windows machine. IP won't be the one from the Windows machine but the traffic, like said, will flow through the same physical interface.
Secondly, you need to use a bridged adapter. For the details you can find help here: Bridged networking not working in Virtualbox under Windows 10

Connect to virtual machine through bridged port

In my setup, I have a virtual machine in VMWare for development purposes using a bridged adapter. I can connect to it from another computer, but not from the host machine. My host is located at 192.168.1.16 and the guest is 192.168.1.10. Both can connect to the internet, but not to eachother. Upon pinging one IP from the other, I get a Request timed out from my host (Windows 10) and Destination Host Unreachable from the guest (Ubuntu Server 16.04.1). Is this a limitation of the bridged connector? Or is there some config that I have missed in making this happen?
EDIT: I am connected to my router using an ethernet cable, and the network is listed as a 'private' one
Can you connect to your host computer from the other (Non-VM) computer?
This sounds to me like your host computer is blocking incoming and outgoing pings which is probably a firewall issue. Try ensuring that you're on a "private" network instead of a "public" network.
The best way to check is by going to the Network and Sharing Center and looking for your bridged adapter. If it says Private network (or Domain network) That's not your problem. If it says Public network, you'll have to change it.
The easiest way to change it is to make sure that's the only network you're connected to and go to "Network" (Just type it in the address bar of any explorer window) A yellow bar will drop down telling you that you're not allowing file sharing on public networks. Click on it and you can get a box that lets you either share files on public networks (NO!!!) or change the network you're connected to, to a private network. (Yes!)
Hope that fixes your problem!

Can machines communicate via serial port without having network adapters?

In VMWare, I have two virtual machines which are connected to each other through a named pipe. Can they communicate with that serial port or do I need to enable the network adapters ?
Configure VMWare to connect the serial port of one VM with the serial port of another. This is the virtual equivalent of plugging a null modem cable into the serial ports of two physical computers. Then, setup a null modem connection, where you network over PPP (Point-to-Point Protocol) just like the old analog modem days.
That said, why do you want to do this? Serial connections are very slow and are commonly used when a very simple, dumb, low level connection is needed. If you want to isolate traffic between two computers, create new virtual NICs on each and add them to the same, separate virtual subnet. This will be much faster, means you do not need to connect and disconnect over PPP and the existing VMWare management and monitoring tools work with it.

How to connect wireless network adapter to VMWare workstation?

How can I connect wireless network adapter to VMWare workstation ?(My Host OS is Windows 7 Ultimate, my Guest OS is Fedora 13 & my VMWare version is 6.5.0)
I'm running Windows 7 on my Dell Vostro A860 laptop & my wireless network adapter is Atheros.
Workstation doesn't have a wireless NIC type, so direct wireless hardware access is out. If you just want to access through the extant host wireless connection, bridging is your answer.
I think the only way to get a wireless NIC dedicated to the VM would be using a USB wireless NIC as a USB-passthrough device on the VM. When you have Workstation running and a USB device plugged in, it should give you an option to change whether that device is connected to the host or to the VM.
Add a local loop network in your normal PC (search google how to)
Click start -> type "ncpa.cpl" hit enter to open network connections.
While pressing Ctrl key, select both your wireless and recently created local loop network. right click on it and create the bridge.
Now in virtual network editor in vmware, select the network with type "Bridged" and change Bridged to option to the recently created bridge.
You will then have access to network via wifi card.
Use a Linux Live cd/usb and boot an that to be able to directly connect to your wifi hardware or use linux as the main OS with direct access to the wifi card and then use windows as a guest os, I know that this maybe not the ideal way but it will work.
I also encountered a similar problem. I run Ubuntu 11.04 on VMware on a Windows 7 host OS. Virtual machines can't expose the physical wireless cards. All of that is using a virtualization layer.
Since there is only one WiFi hardware on the computer its not possible to connect one WiFi hardware to multiple WiFi networks, if you want to that I think you have to map WiFi hardware to guest OS and how host you'll have to use some other hardware (may be Ethernet) but I'm sure that it will work in that way as no VM software allow us to allocate Hardware to Guest except for USB, you can also get USB WiFI and allocate that to VM only.
Change your network adapter to a bridged connection, this will directly connect to your computers physical network.
Here is a simple way to connect with your WIFI -
Click on Edit from the menu section
Virtual Network Editor
Change Settings
Add Network
Select a network name
Select Bridged option in VMnet Information -> Bridge to : Automatic
Apply
That's it. You might be asked password to connect. Add it and you would be able to connect to the network.
Kind Regards,
