Issue adding multiple DNS servers on Linux Mint

Hi All,
I recently created vm box with Linux Mint, but im having issue adding multiple nameservers.My VM is set up with NAT.The issue i'm having is, if i set my DNS to 8.8.8.8 through network manager, im not able to resolv names on internal network, but if i change dns settings to use the internal server i cant resolv anything on internet. I tried everything i could think of, until my system got messed up.

How is your internal DNS server configured? It should be set to fall back on an external DNS if the name isn't on its list.

Not sure about the internal dns server config. I don't have access to it. What i recently tried was editing /etc/dhcp/dhclient.conf/head
and adding few dns entries. Also,commented out dns=dnsmasq line in /etc/NetworkManager/NetworkManager.conf then restarted network manager.
When i do cat /etc/resolv.conf , i can see the dns entries i made in dhslient.conf, but when i right click on network-manager and click on Connection Information ,i don't see any DNS

Also, i just used nslookup and found out that when i do nslookup www.yahoo.com i get:
[code]
;; Got recursion not available from a.a.a.a , trying next server
[code]
I'm not sure why is this happening. In dhclient.conf file the order is following:

Code:

supersede domain-name-servers 8.8.8.8, a.a.a.a;
