Resolving Guest DNS While Connected to Campus VPN
If your Virtualbox Guest cannot resolve DNS while the host is connected to campus VPN -- do the following:
Find the name of the active guest
While the guest is active, run the following command on the host to get the name of the guest.
VBoxManage list runningvms
If the command is not found, then it is not in the working PATH.
On Windows hosts, the command is usually located
C:\Program Files\Oracle\VirtualBox

With the name of the VM, issue this command, next:
VBoxManage modifyvm "VM Name" --natdnshostresolver1 on
