Best way to segregate my network

I have a small network of about 50 PCs all running windows 7 and in a AD environment. I also have 10 machines that process credit card information, I want to segregate my network so the 10 machines are not seen by the other 40 users. Currently I have a Sonicwall TZ205W and have non managed switches in between, is there a way to configure the sonicwall to segregate my network? what will be the easiest approach to do this?

Why not have users on a different VLAN than your credit card machines and then have firewall/routing rules in place where network communication is only available in one direction or not at all.

Can you just put the 10 devices on another switch that connects to a different port on the sonic wall and then limit traffic between the two networks?
Steven CarnahanNetwork ManagerCommented:
Since you are running unmanaged switches I would isolate the CC machines on one switch. Connect that switch to one interface/port on the Sonicwall TZ205W and everything else through a single switch to another interface/port on the Sonicwall TZ205W.  The configuration to isolate will need to be handled by the Sonicwall TZ205W

EDIT:  While I was being so wordy in explanation I see that Bryant basically said the same thing.  :)

un-manage switch makes it hard to setup up vlan, howto tag the traffic, separate switch and network.
Steven CarnahanNetwork ManagerCommented:
Place two interfaces in the same zone (probably LAN) but do not select "Allow Interface Trust".  Selecting that permits hosts on the interfaces to communicate with each other.  Then put the 10 devices that process card data on a single switch and connect it to one of the interfaces and place all others on the other switch connected to the second interface.
