I have host Windows 10 with Cisco anyconnect VPN to my work net. VirtualBox with Linux Mint.
So when Vpn on host isn't enabled everything works fine. But when I connect vpn, my VM gets access to work net, but all other sites can't be resolved.
VBoxManage modifyvm "VM name" --natdnshostresolver1 on - does not helps, it works for some time but after I reboot host or guest (doesn't remember what I tried already), I can't get access to my vpn network, despite vpn is on.
As I can see dns server added in UI (188.8.131.52) appears in output:
Global DNSSEC NTA: 10.in-addr.arpa 16.172.in-addr.arpa 168.192.in-addr.arpa 17.172.in-addr.arpa 18.172.in-addr.arpa 19.172.in-addr.arpa 20.172.in-addr.arpa 21.172.in-addr.arpa 22.172.in-addr.arpa 23.172.in-addr.arpa 24.172.in-addr.arpa 25.172.in-addr.arpa 26.172.in-addr.arpa 27.172.in-addr.arpa 28.172.in-addr.arpa 29.172.in-addr.arpa 30.172.in-addr.arpa 31.172.in-addr.arpa corp d.f.ip6.arpa home internal intranet lan local private test Link 3 (enp0s8) Current Scopes: none LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no Link 2 (enp0s3) Current Scopes: DNS LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no DNS Servers: 172.30.0.14 172.30.0.15 10.2.2.2 184.108.40.206 DNS Domain: ~. net.mycompany.ru
I don't know how to tell that system to try one more dns. 10.2.2.2 - is my home router - gateway, dns ip. Can it be related with that fact that my home network uses 10.2.2.* addresses?
