Before installing VirtualBox or VMware Workstation, my VPN Connection (L2TP/IPSEC PSK) works without any problems. I'm able to reach every Site I want.
But after one of them are installed I getting this error message at several sites with Chrome (Edge and Firefox won't load too, but without giving me an detailed error message), e.g. the whole StackExchange Network.
My Android Phone didn't have this issue (connected to the same VPN, of course)
I tried all the nice things that i found with google.
flushing/renew/release dns (and other crazy command line commands) -> no success
Set DNS-Server manually -> no success
Even after uninstalling -> no success
2 weeks without Vmware/VirtualBox (after complete Windows-Reset) -> SUCCESS
My question now: Is it possible to get back the functionality without to give up on VirtualBox or Vmware? Any Ideas, some magic spells?
Server = QNAP-NAS
Client = Windows 10
Many thanks.

VMnet1 is the Internal Network (To connect via SSH without a physical network)
VMnet8 is the VMware Bridge
Connecting to the local Network devices via IP (192.168.0.xx) over VPN works fine.
As i mentioned earlier, the other half of the world wide web is reachable.
1Please run
nslookup -d2 inaccessible-site.com
(i.e. Use a hostname you cannot access) and [edit] your question with the output, then ping me. – I say Reinstate Monica – 2018-01-05T22:26:04.193@TwistyImpersonator : I have updated my post with the output of nslookup. thanks – reinholda – 2018-01-06T07:41:38.637
Your edit shows that the DNS server at 192.168.0.1 is not responding. Is this the DNS server you intend your computer to use? Is it the server that gets used when everything works correctly? Please [edit] your question to include what IP addresses your computer and your VMs are using, and your router. Post the output of
ipconfig /all
. – I say Reinstate Monica – 2018-01-06T14:18:10.827192.168.0.1 is my Router IP. If i use an other DNS Server (e.g. Google or OpenDNS) this Problem still appears. (Setting on Client and/or Server, still not able to connect). Is the installed Bridge Network Adapter from vmware/vbox causing this issue? Without the Virtual- Software evrything works fine. – reinholda – 2018-01-06T14:30:08.367
Sry. Forget to "Ping" you @TwistyImpersonator – reinholda – 2018-01-06T14:31:50.290
Does the IP addressing of your VM stations conflict with the IPs used on your physical network? It sounds like traffic intended for your router is going to your VMs instead. – I say Reinstate Monica – 2018-01-06T14:50:08.330
@TwistyImpersonator What do you mean with conflict ? My VMs received the IP over DHCP from my Router. (My Routers IP is '192.168.0.1' and the IP of my VM is '192.168.0.104'). – reinholda – 2018-01-06T15:35:45.690
None of your network adapters has an IP address in the same subnet as your router's IP of 192.168.0.1. This is why you cannot perform DNS lookups using the router. Which of these adapters is connected to the Internet? – I say Reinstate Monica – 2018-01-06T17:27:17.927
@TwistyImpersonator It's "Mobiler Breitbandadapter Mobilfunk". I use the LTE Modem of my Notebook. Why is e.g. Google.com usable over vpn, but superuser.com isnt working? – reinholda – 2018-01-06T17:37:50.217
I'm surprised any web access is possible. It looks like your adapter binding order has your VPN connection ahead of your mobile connection. When I get off mobile I'll find the steps to address this. In the meantime, can you disconnect the VPN connection? If so, does that help? – I say Reinstate Monica – 2018-01-06T17:41:34.050
@TwistyImpersonator yes, without the VPN connection everything works fine. It doesnt matter if i use mobile or a "real" network. With VPN enabled, the DNS error appears on some sites. Strange. MANY THANKS TO YOU – reinholda – 2018-01-06T18:01:43.663
so does disabling the VPN connection solve your problem? Or do you need things to work while the VPN is active? – I say Reinstate Monica – 2018-01-06T18:53:56.910
@TwistyImpersonator
>Or do you need things to work while the VPN is active?
Short answer: Yep! thanks again for your time. – reinholda – 2018-01-06T19:07:04.660Try this. I didn't want to post it as an answer unless it works (since I'm still a bit unclear what you're actually after).
– I say Reinstate Monica – 2018-01-07T22:32:00.397@TwistyImpersonator No, i tried this before, without luck. If i Removed the checkmark from "Standardgateway for the Rmotenetwork" – reinholda – 2018-01-08T16:36:44.480
Why do you have the DNS server 192.168.0.1 configured on your VPN at all? – I say Reinstate Monica – 2018-01-08T16:39:52.233
.... i was able to visit superuser.com but cannot connect to my local devices :( The IP 192.168.0.1 (my Router) is given by the qnap. I have changed this to 8.8.8.8 but without luck. I even changed the Metric Values from the Network Cards. And again without luck, – reinholda – 2018-01-08T16:47:48.967
Which of your interfaces is connected to your local network? That's where your local DNS server should be configured. – I say Reinstate Monica – 2018-01-08T16:50:49.820
@TwistyImpersonator i give up on L2TP/IPSEC. Switched to OpenVPN. No DNS related issues. I'm able to browse the (complete) web AND use my local devices at home. Thanks! – reinholda – 2018-01-10T15:14:28.457
