Insted of setting up a bunch of VLANS for only 4 devices, try writing
an ACL table restricting the IP's of those devices OR you could setup
the VLANS and just segregate the Subnets you want through your ACL.
Either way I think your going to have to write an ACL for your setup.

Hope you figure it out.

Chris.

No.
VLANs as do R(eal)LANs separate their members, which can happily
communicate, from the rest. Imposing policies on hosts has nothing
to do with LANs.

Sorry Jerry,
An ACL stands for Access Control List. It's a table that has a list of
instructions setup to allow or disallow protocols, subnets, hosts,
servers, etc. to talk with each other. It sits on your router and acts
as the police of the network.
