Internet is not working after using VirtualBox

[ranga]

Dear Team,

I have installed virtual box 5.1 in my fedora-26 pc , where i have made successful installation of vagrant inside virtual box , then docker inside vagrant by which i am trying to install ansible via docker.

my host machine ip is : 192.168.2.6
my virtual box ip is : 192.168.2.150

setup is as follows
Host > Virtual box > Vagrant > Docker > Ansible
Default Gateway for both Host and Virtual box is 192.169.2.1

i am able to ping Default Gateway 192.168.2.1 inside virtual box as well as 8.8.8.8 also where as from host am unable to ping default gateway 192.168.2.1 but sometimes i can ping 8.8.8.8 from host pc

Can any one help me in this

Thank you.

1. Nested Virtualization is not supported.
2. Vagrant is a program that relies on VirtualBox but modifies its configuration files in unknown ways to us. It is not supported on these VirtualBox user forums, they have their own Vagrant support channels. If you are having this problem with a standalone version of VirtualBox, then we can continue this discussion.
