internet not working in virtual machines problem set 1 of experiments

Jump to solution

I am trying to play with various kind of scenarios and configurations to understand VMware Workstation networking.

So here is one setting of virtual network editor.

There is no internet connectivity in Virtual machines.

There are 2 Wifi Cards on this system

Wireless Lan adapter Wifi: Realtek

Wireless Lan Adapter WiFi 2:D Link USB Wifi Adapter

The Host OS is connected to internet from both WiFi cards.

I am a bit confused in virtual network and network adapter settings in virtual machines.

I can ping from virtual machines to host OS both Lan cards.

But from host OS I can not ping to virtual machine.

Also I do not know how to use different different wifi card on host OS for ping to virtual machines.

This is solved with the help of a comment here

https://serverfault.com/questions/994722/nslookup-failures-unknown-cant-find-www-vmware-com-query-re...

they suggested me to put my ADSL router IP as DNS IP in virtual network editor in vmnet8--->NAT settings--->DNS settings

here is a screenshot how DNS setting looked previously in virtual network editor vmnet8---NAT ---settings--->DNS

kd vne dns config.jpg

after that comment on serverfault I changed the setting as below 192.168.1.1 is my ADSL router IP

kd 9 12 2019 dns host  2.jpg

now I did a nslookup from within virtual machine

kd 9 12 2019 nslookup vm 1.jpg

ipconfig on host OS shows following

kd 9 12 2019 ipconfig host  3.jpg

the DNS server in the above Ipconfig output is not 192.168.1.1 it is automatically given by ADSL router but for VMware environment

I had to set it, and now my virtual machine has internet connectivity.

Here is a screenshot

kd 9 12 2019 vm internet 5.jpg

So it is working now. Thanks for your suggestions as your suggestion for

nslookup helped to dig this further.Let me know if any thing else you want to suggest.

But nslookup from within the virtual machine still fails I don't know why. The screenshot I have attached for nslookup from vm.

A common reason for not being able to ping the guest OS is the guest's firewall. I case of Windows you may need to allow ICMP 8ping) traffic on the guest's firewall.

Once you ping the guest' IP address, the host will determine the route based on its known routes (command: route print) Since the host has a "Host virtual adapter" for the NAT network, it will use the that one to connect to the guest.

Why you cannot reach the Internet is another issue. It may be worth trying this with only a singe active network adapter on the host.

Are you able to ping e.g. 8.8.8.8 from the guest OS?

Yes this is very surprising I am able to ping 8.8.8.8 from the guest OS

I did ping twice to be very sure that it is actually happening.

Here is a screenshot.

gues ping to 8888.jpg

firewall of guest OS is disabled screenshot below

firewall in guest is off.jpg

firewall of host os is on screenshot below

firewall in host is on.jpg

It may be worth trying this with only a singe active network adapter on the host.

Yes you are right I did so and that discussion I was having here https://serverfault.com/questions/994622/internet-connectivity-failure-in-virtual-machines-on-workst...

so let me share the results here also on that serverfault link the result I posted was in comment here  ​  I had one by one disabled both the interfaces and there was no success in getting internet connectivity inside VM.

I had also tried with ethernet cable  and there was no success. Your suggestion of ping to 8.8.8.8 is new thing and this I had not tried.

Right now I am in an environment where I can have a ethernet connection but after 30 days I will be back to where I can not use ethernet. Back in my institute I get internet only via WiFi interfaces not by ethernet. Lan wires simply don't exist at that place. Now coming to the problem why I posted here I have been facing this configuration problem from past 2 months look at this question and answer

https://superuser.com/questions/1495476/internet-disconnects-after-switching-on-virtual-machine-in-b...

I posted in October in which I tried to do a bridging between a wireless AP and my VMware but it did not worked reason for this is mentioned here

  in past 24 hours what I have been trying to figure out you can see the discussions here connecting virtual machines to desired vmnets

this was something I could not check and my environment changed.
By environment change I mean I had internet access via wifi from my institute now I am 1500 kilometres away from my institute now  I access internet via ADSL router broadband connection.
Configure vmware workstation so that virtual machine gets IP from wifi router communities.vmware.com/thread/618041 wifi router means access point which is at my institute and I get to login via captive portal to connect to internet and I have a limit of 3 devices to bring on in network in institute. One laptop one mobile phone and then if I try to connect 1 VM I am out of my options to run more VM which I need to run for educational purposes. I am having cloudera and Ubuntu VMs have to run Hadoop clusters but all fail to connect to internet because I need a lot of things which depend on internet in virtual machines.
I was previously doing all this where I had wifi access by institute under a restricted environment.
Right now at my location for next 21 days and I can have any kind of configuration tested on wifi or ethernet,
because here no firewall or wifi restrictions are present. But when I will be back to institute then I have all kind of problems there. We have a Sophos firewall there and internet connectivity is there by Wi-Fi only no LAN wires at all. If VM does not connect to internet here in this scenario in NAT it wont work there in institute.
Unfortunately the people there don't understand my problem and since I could not give assignments on time I have suffered a lot in my grades in assignments and projects which need these virtual machine each assignment I have is a new circus all together. ( I do not know a better word than circus please suggest if you know better word).If you think you have any answer for scenarios I mentioned in above links then do comment here I will check. I am facing a tough time.Any thing you ask me to test I will test.

Which version and build of Workstation are you on? That VMnet0 adapter showing Custom type is odd, not sure how you get a network like that. May try a reinstall or repair to make sure the configuration is clean.

someone had replied above by the time I refreshed they had deleted the comment but I could get what the persons doubt was so I am posting a screenshot of ip address of my guest virtual machine.

virtual machine ip .jpg

in the screenshot above if you notice the ip address of virtual machine is 192.168.152.128

the output of ipconfig is


Windows IP Configuration


Ethernet adapter Ethernet0:

   Connection-specific DNS Suffix  . : localdomain

   IPv4 Address. . . . . . . . . . . : 192.168.152.128
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.152.2

and I again post a screenshot of virtual network editor

virtual network editor1.jpg

dhcp service is running on vmnet8 and the ip addresses it is broadcasting are in range 192.168.152.x

so this is working fine in my understanding.

ping to 8.8.8.8 is also happening from virtual machine.But if I open a link like https://www.msn.com/en-in/?ocid=wispr&pc=u477 in edge then that is not displayed.

I am on

Workstation 15 Pro

15.1.0 build-13591040

as far as you ask about vmnet0 custom thing I had messed it up I have had problems so I kept on trying various configurations and now even I don't remember how I did that.

Change VMnet0 back to bridged and check the box to connect a host virtual adapter to to this network. Workstation may internally use this virtual adapter to know where to route NAT traffic out of the host (unsure), so disconnecting may essentially be removing any network access to VMs? I also read your other post about making sure the NAT traffic goes out a WiFi adapter. You could also select the VMnet0 "bridged to" to one of the WiFi adapters instead of automatic to make sure it is not trying to route traffic out a disconnected Ethernet on the host.

If you are licensed, you also should be able to upgrade to 15.5 (latest version released), in case there is a bug in your version.

that box you mention to check out

check the box to connect a host virtual adapter to to this network.

is greyed out see the screenshot.

box is grayed out.jpg

I can not tick this box. Connect a host virtual adapter to this network.

You could also select the VMnet0 "bridged to" to one of the WiFi adapters instead of automatic to make sure it is not trying to route traffic out a disconnected Ethernet on the host.

yes this is what I was actually doing when I think I messed with vmnet0 custom thing and many other things I did a lot of screenshots I have a lot of screenshots.

I am on a poor internet connection where uploading 53 JPEG images (folder size 22.5 Mb) in google drive takes several hours.

ping to 8.8.8.8 is also happening from virtual machine.But if I open a link like https://www.msn.com/en-in/?ocid=wispr&pc=u477 in edge then that is not displayed.

This looks like a DNS resolution issue.

Please run ipconfig /all in the guest OS to find out whether the DNS server address is configured (which should actually be the case).

To test name resolutionrun e.g. nslookup www.vmware.com to see whether it resolves to an IP address.

Not sure what's blocking the DNS query. Maybe group policies/local restrictions on the host!?

Please open a command prompt in elevated mode (i.e. run "As Administrator"), then run the following commands, and post the output in your next reply.

ipconfig /flushdns

nslookup www.vmware.com

nslookup www.vmware.com 8.8.8.8

these commands should be run from guest OS or host OS

what I have now done is I read a document here kb.vmware.com/s/article/1008367 in point number 8 To restore the networking defaults, click Edit > Virtual Network Editor and then click Restore defaults. so I did restore defaults . Rebooted the virtual machines. Now every thing I am doing fresh.

After a reboot of all virtual machines and restoring default in virtual network editor

on the host machine I have following


    C:\WINDOWS\system32>nslookup www.vmware.com
    Server:  UnKnown
    Address:  109.169.85.7
   
    *** UnKnown can't find www.vmware.com: Query refused


but I can access the site in browser this is on host OS.

Every thing is working fine perfectly.


when I do ping from a VM to host I can ping and get reply.

now from virtual machine I executed your commands

C:\WINDOWS\system32>nslookup www.vmware.com

    Server:  UnKnown

    Address:  109.169.85.7

   

    *** UnKnown can't find www.vmware.com: Query refused

Since you are already getting this error on the host, you may want to check the IP settings on your network adapters.

It looks like the DNS server address is incorrect.

Here is a screenshot of DNS settings on my WiFi adapter on which virtual machines should get internet and I am posting questions here

kd dns setting automatic on host.jpg

I do not have the expertise to understand what is the mistake in above configuration.

Every thing any website which I browse on host is  accessible and internet is working

fine on host OS with above configuration. Moreover the current environment where I am accessing

will change after one month when I go back to my place where I have to be for next 6 months.

There we get internet only via Wi-Fi so I have to share internet with virtual machines in NAT only.

But any how that is not a part of this question. I just want internet to be available to virtual machines

in current scenario. What should I look more to debug the problems that I am not able to understand.

The issue is most likely not caused by the guest, nor the host, but by the settings in your WiFi router, i.e. the device with the DHCP server. The DNS settings there seem to be incorrect.

That is an ADSL router which in broadband connections is accessible for home users by http://192.168.1.1 I do not know what to check in it.

The ADSL router model is Dlink  Product Page: DSL-2750U

here is a screenshot of DNS settings page in router

I do not want to touch it because I do not have the expertise for this.

Probably these settings are given by the vendor who installed this originally. Please how do I edit my response on forums I do not know

what this black square boxes have come in my post.

I'm not familiar with D-Link routers. However, the usual setup is to set the DNS server address in the router's DHCP settings to the routers internal IP address (i.e. 192.168.1.1 in your case). With this setting the router will receive its public settings from the ISP, and your internal devices will receive private settings from the router. With such a setup, a DNS query from your host will be sent to the router, and if it doesn't already have the requested information, it will forward the DNS query to its known public DNS servers.

This is solved with the help of a comment here

https://serverfault.com/questions/994722/nslookup-failures-unknown-cant-find-www-vmware-com-query-re...

they suggested me to put my ADSL router IP as DNS IP in virtual network editor in vmnet8--->NAT settings--->DNS settings

here is a screenshot how DNS setting looked previously in virtual network editor vmnet8---NAT ---settings--->DNS

kd vne dns config.jpg

after that comment on serverfault I changed the setting as below 192.168.1.1 is my ADSL router IP

kd 9 12 2019 dns host  2.jpg

now I did a nslookup from within virtual machine

kd 9 12 2019 nslookup vm 1.jpg

ipconfig on host OS shows following

kd 9 12 2019 ipconfig host  3.jpg

the DNS server in the above Ipconfig output is not 192.168.1.1 it is automatically given by ADSL router but for VMware environment

I had to set it, and now my virtual machine has internet connectivity.

Here is a screenshot

kd 9 12 2019 vm internet 5.jpg

So it is working now. Thanks for your suggestions as your suggestion for

nslookup helped to dig this further.Let me know if any thing else you want to suggest.

But nslookup from within the virtual machine still fails I don't know why. The screenshot I have attached for nslookup from vm.
