Virtualbox bridge.

I use virtualbox at home on my fedora 27 server and bridging to the local interface I have no issues.

I use Ubuntu 16.04 at work and have been trying to bridge the guest OS to eno1 network interface but I am having no luck. I can't seem to find a working solution.

I tried setting promiscuous mode on the interface and on in virtualbox.
I still can not get an ip from my networks dhcp server.
It seems something is preventing my user from using the interface to get an ip for the guest OS.

I tried creating a bridge interface by adding

auto br0
iface br0 inet dhcp
bridge_ports eno1
bridge_stp off
bridge_fd 0
bridge_maxwait 0

to /etc/network/interfaces
and restarting networking via

/etc/init.d/networking restart

then I tried creating tun0 via
ip tuntap add tun0 mode tap user myusername

then as soon as I run the following my machine stalls and I have no alternative to hard powering off and on again

ip link set tun0 master br0

# lspci|grep Ether
00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I217-LM (rev 04)

It seems networking on ubuntu is broken horribly.

I am using active directory users in ubuntu via samba I'm not sure how that would make a difference.
I was going to try fedora 27 in a vm to see if I can start using it with the same smb.conf I use to join my ubuntu and centos here at work but I am fighting with virtualbox on ubuntu 16.04

So my questions are:

What would be preventing my user from setting up a bridge to the eno1 interface? Is there a way to allow my users

Am I doing something wrong when I try to bridge tun0?
