Ubuntu 17.10 host, Virtualbox 5.1.34_Ubuntu r121010.
In Virtualbox I have a couple guest systems Windows 10, Linux Mint, Fedora that had been working just fine, they had internet access. They all were set up with the NAT attachment.
Yesterday, for some reason I cannot figure out, they all lost internet access.
When I experimented and change the attachment setting from NAT to Bridged, they all again had internet access.
How can I figure out what the problem is with the NAT attachment setting?
