You should look into IPsec that's on the O/S to secure the LAN between
the machines. The AnalogX SecPol file when implemented on each machine
will provide that protection.

Also, one needs a stand alone AV on each machine as there are more than
one way to have a machine compromised with malware, which usually happens
with *happy finger* users behind a gateway device that's providing

Lastly, if you have no reason not to be using a NAT router as the gateway
device for the LAN and WAN, then may be you should look into getting one
as they provide better protection and are cheap, like $20. And you can
plug a standalone hub or switch in to the LAN port of the router to
extend the network.
