Wifi adapter wrongfully answers to an ARP request

Asked by Gregorio I Becerra on 2020-06-19

Hi,

wish all of you are well.

I just bought a new TP-link M5 deco mesh router (set of 3). Everythin works fine (can navigate, connect to other devices, etc, but when I start a virtualbox VM, when the router asks (via ARP request) who is using a given IP (which was assigned to the VM by DHCP), both the VM and the host machine reply to this request, generating a conflict. The router wrongfully register the host as the IP owner overriding the previous VM answer to the ARP request.

First, I contacted TP-link, and after they analized the wireshark capture they requested, they concluded the wireless adapter is doing something it should not do. I reviewed myself the capture file, and indeed there was the duplicate answer for the ARP request.

This does not happen If I use my wired connection. Only in wifi. It happens with all 10 VMs I use. Because of this last fact. I am inclined to think s a problem with the wifi adapter. If it were a virtualbox problem it would show either by wifi or by wired connection.

This router uses ARP to verify which device is using what IP at any given moment, and registers the device in a list shown to the user via a phone APP. Thus, the VMs never show up on the list. The VMs show up on the APP only if the host is linked by wire.

Hope you can help me solve this.

I am running Kubuntu 20.04 LTS on dell precision workstation M7520, Wireless interface 8265 / 8275 Intel Corporation. Connected to ITN network by wifi. Using virtualbox 6.1.6 from official repo. VMs are Win7, win8, ubuntu 18.04LTS 20.04LTS both servers and desktops.

This is the info captured with wireshark:

Try running the VM NIC in its own network rather than getting an IP from your router. May help

Manfred Hampl (m-hampl) said : #2

Who is using the wireless device?
The Linux host, or the virtual system, or both?

Gregorio I Becerra (gregorib) said : #3

My dell M7520 has the physical wifi adapter, the VM has configured a regular intel pro 1000 "desktop" adapter, but is bridged to the local network though the host wifi adapter. VM isolation behind NAT is not an option.

What OS is the guest and what OS is the host, please?

Gregorio I Becerra (gregorib) said : #5

Hi, thanks to all for the help,

I am running Kubuntu 20.04 LTS on dell precision workstation M7520 (HOST), Wireless interface 8265 / 8275 Intel Corporation. Connected to ITN network by wifi. Using virtualbox 6.1.6 from official repo.

VMs are Win7, win8, ubuntu 18.04LTS 20.04LTS both servers and desktops.

Does the networking in the Windows VMs work OK? Isolating behind a NAT is an option you just have to perform more config on the network side but it can work.

Gregorio I Becerra (gregorib) said : #7

Hi,

thanks for your help and interest.

I researched the NAT alternative, and according to virtual box documentation, there are some possible issues regarding port forwarding and non privileged port use that make this option a no-go.
If it were just a machine, I would go and try to make it work, but since there are several VMs involved in the work I do, I believe it is easier to try and fix the original problem, instead of using a more complicated workaround. I understand this is an option, but is not a solution to the problem at hand.

Any suggestions about which would be the host component causing the problem besides the wifi driver, if there is something else to blame for the problem?

Again, thanks for your help!!!👍👍

Manfred Hampl (m-hampl) said : #8

Just to understand your setup:
You have several VMs running (windows, linux, ...).
Are they running at the same time?
Which one of them is wrongly responding to the ARP request? Each of the Linux ones, or just a single one, or also the Windows guests?
Do you see the WLAN hardware from inside the Linux guests?

Have you considered upgrading to the newest version of Virtualbox (6.1.10) from virtualbox.org?

Gregorio I Becerra (gregorib) said : #9

hello,

thanks 4 your answer. Below I respond to your questions:

Are they running at the same time?
> Nop, but sometimes there are 3 or 4 running. Those are used to simulate network nodes.

Which one of them is wrongly responding to the ARP request? Each of the Linux ones, or just a single one, or also the Windows guests?
>None of the VMs answer wrongfully, is the host which also responds to the ARP request, and should not do it. It is in the Wireshark trace I submitted earlier. Host is on ip 123, and should not answer ARP for IP 105, which is the VM IP.

Do you see the WLAN hardware from inside the Linux guests?
>Nope, there is no need for this.

Have you considered upgrading to the newest version of Virtualbox (6.1.10) from virtualbox.org?
>That would be the next troubleshooting step, but reading the changelogs, it seems fixes are irrelevant to this problem. Also, since started using 20.04, I find better to use official repo. When first installed 20.04, app was using the wrong scaling and had to fix qt5 settings, and experienced some other problems related with the video adapter used by the guest VM, and kernel signatures. Maybe those problems are gone by now, but I have not had the time to do this step. Have to use a side machine to test it. Do not want to mess with current setup which is working.

Hope this clarifies things.

Manfred Hampl (m-hampl) said : #10

Thank you for clarifying that the _host_ is wrongly responding.

Does the host give that wrong answer also when the virtualbox guest is not running, and/or when the virtualbox software is not running?

Gregorio I Becerra (gregorib) said : #11

Hi,

tried Virtualbox 6.1.10 without any luck. I reviewed on both installations and the problem presents once the VM node starts, after doing their DHCP request.... a while later ARP broadcasts begin and then it is when the problem shows up. Fore some reason the host wifi adapter thinks it owns the ip which belongs to the guest VM.

Tried pinging the guest VM from my phone, and when my phone does the ARP process to find out the MAC of the host to ping, both guest VM and host wifi answer they are at the IP to be ping. it should be only one answer. Reviewing all ARP traffic, once the guest VM is down, host wifi realizes it has original IP and asks who is the owner of the guest VM IP.

There is something going on when the VM is up and running, no matter if ip is assigned static or via DHCP, once it starts, the host wifi thinks it has the same IP as the guest VM, and the problems begin.

Any ideas will be appreciatted.

Gregorio I Becerra (gregorib) said : #12

Hi,
after reviewing virtualbox documentation chapter 6, https://www.virtualbox.org/manual/ch06.html#network_bridged
and consulting on virtualbox forums, it seems that the problem is the expected behavior in such setups. There is a workaround using macvlans, which will research.

Thanks for your help!
