	This can be achieved with the combination of a router and a managed
switch. Assign each node its own VLAN and set the switch up so that each
node's port is on the node's VLAN untagged and the routers port is on all
the VLANS tagged.

	The router provides routes between the internet and the VLANs but
not between the VLANs and enforces this with firewall rules.

	Essentially this is like having a router with a lot of ports and
one node on each port (which is another solution).

	If your nodes are on a wireless LAN then the AP can probably
isolate them from each other for you.

	This is good advice and simpler - if you want enforced isolation it
is more complex.
