Sure, a host-only adapter probably make this easier than the bridged
setup described in the link.

This is interesting and certainly needs to be investigated further
(added to todo item). My initial testing shows that, indeed, bridged
adapters bypass the host's firewall.

Allowing NAT is at least not a leaking-related problem since the NAT:ed
traffic appears "normally" in the host OS, so in Tails it will be caught
by the firewall.

vboxnetflt is used for bridged adapters, but host-only adapters requries
*both* vboxnetadp and vboxnetflt to be loaded.
