[other] Virtual Box NAT Networks - No Internet Access

I have created a aNAT Network in VirtulBox 5 In Ubuntu 14.04 LTS with followingsettings

Natework Name :NatNetwrok1
Network CIDR:10.0.2.0/24
Support DHCP:enabled
Support IPv6:disabled
without any portforwarding

Additionally I havetwo VMs (Both Xubuntu clones), I have set the Network settings toenable two NICs on each of the VM with following settings in allfour adapters:

Attached To : “NATNetwork”
Name :“NatNetwrok1”

When I run both VMsI can see following settings on running ifconfig command

ifconfig results onXubuntu1

Ping between these 4IPs works fine
But I can not accessInternet on either of these VMs
While if o change“NAT Network” to “NAT” I can access the network but it seemsthe become part of different virtual network and I can not ping themfrom each other
Can anybody help mein identifying and fixing problem
