My redhat (guest OS) having issue for not able to resolve the hostname like google.com but able to ping 18.104.22.168.
I didn't do anything at all just to ensure that it can ping Google first and my network subnet like 192.168.1.0/24 when my redhat added a NAT Network adapter without issue.
After that I connect my fortinet vpn client thr IPSec and still can ping and resolve my private cloud thr hostname.
Next day I do the same thing like connect to my iPad 4G network to my Hp laptop wifi.
Can ping and resolved on my hp laptop even being connected to vpn.
The guest os redhat from virtualbox on nat can ping 22.214.171.124 but not able to resolve now.
Why yesterday can and today can't without changing anything?
