two network LAN and WAN

[seaside_101]

hi,
we have two network.
LAN for internal network and WAN for external and internet network.
We have two system for these networks.
I want one system for both of these network, Can I have do this?

Note: the internal network (LAN network) needed security because we have software and information about patients treatment. For this reason, we didn't connect these system to internet.

Too vague. I don't understand what is SYSTEM in this context?

Boy, you think you explained this clearly but I have not the faintest idea what you want.

Your said you are keeping LAN separate from WAN for security purposes, then you say you want 1 box to do both. If this 1 box is able to do both then your LAN won't be secured any more.

If this a homework question? Are we dealing with a business yes? What is your IT guy says?

To be 100% secured, you don't allow any of the boxes to access the Internet, and I mean, no connection whatsoever, and disable all removables and USB connection also. Am sure you heard of StuxNet. The extract/input data into this secured LAN, you use some highly controlled, single entry/exit procedure.
