TB18 dock: how to configure the ethernet port?
I have a Dell Precision 7530 (ubuntu) and a Dell TB 18 dock.
The dock works fine w/ my external monitors except that the ethernet port doesn't work.
`ifconfig -a` shows:
vboxnet0 Link encap:Ethernet HWaddr 0a:00:27:00:00:00

eno1 is the ethernet port on the laptop.
vboxnet0 is the ethernet port on the TB18.
I read on the TB16 manual that there is support for "mac forwarding":
It is unclear how to enable this under ubuntu.
Any suggestions?

This looks like it is working. It got an IP address from somewhere. Can you be more specific about "not working?"
If you execute:
That is typically your router (I think.) What do you see?
Taking a step back, how have you configured Ethernet? Default is to obtain an IP address using DHCP and that should also get a DNS server.
