Windows TAP Adapter shows "No Internet access"
Posted: Wed Mar 02, 2016 2:24 pm
Well like the title says, on my OpenVPN client the TAP Adapter says it has no Internet access, but the DNS entries are correct and when I try to resolve hostnames over these DNS servers it works fine.
I've set up a caching DNS on my OVPN host with dnsmasq which uses the Google DNS servers as nameservers in a separate resolv file and it redirects requests to *.ho.me domains to my home routers DNS which is also connected to my OVPN host, so I can access my home devices via their hostnames.
My server config:
My home routers ccd file:
My external clients ccd file:
My external clients config:
I also tried to add register-dns but then it just throws an error that it couldn't execute ipconfig /flushdns and /registerdns, even though I started the OVPN Gui with admin rights... But even when I execute these commands manually, it still shows "No internet access"
The output of ipconfig /all from my external client:
I can access my home devices like server.ho.me without a problem, I can also execute nslookup google.com 10.8.0.1 on my external client aswell on my host which works fine so dnsmasq on my host seems to work like it should.
So why does Windows say that my TAP Adapter has no Internet Access?
Is anything wrong with my configs? My external client sits behind a proxy FYI
