NAT'ing on Oracle Virtual Box doesnt works with static host

[Manik]

Hi All,

I am facing the below problem on Oracle Virtual Box. Posting it here
in case anyone has faced the similar issue.

I have a 2 node Juno setup on Oracle VBox.
I have configured one of my interfaces as NAT (For internet access,
package downloads etc)
The other interfaces are configured as Host-Only so that I can SSH
into the VM from my Windows machine.

I have assigned static IPs (192.168.56.*) to these host only
interfaces due to OpenStack configuration.

Observation:
When I give a static IP , the NAT interfaces doesn;t gets IP. When i
run dhclient for the NAT interface, it gets 10.0.2.15 as its IP. Even
after that internet doesn't works.
I have edited nameserver in /etc/resolv.conf, even then it doesnt works.

So the question is:
In a VM having 2 interfaces(NAT and host-only), if we give a static IP
to host only interface (192.168.56 series), the internet access doesnt
works on the NAT interface.

Thanks

There are no reason for it to interfere and there never was an report of such broken behaviour.
The usual culprit is configuring the host-only interface in the host or in the guest with a gateway or DNS servers, which won't work.
NAT requires DHCP on the interface or VirtualBox will not be able to communicate with the guest.
