Small LAN, 5 PCs. How to protect one PC inside LAN(isolate from other PCs):

to prevent from connecting other computers to that PC, or share files?

Several ways:



1) Software firewall on that PC. Block all incoming access and

disable "File/Printer" sharing.



2) Add a separate router. Makes this PC part of a second "LAN"

network and remaining PC would not be able to access it.

1) Windows firewall enabled, but its not secure, allows add expecption

How make sure "File/Printer" sharing disabled?

2) no way add separate router

What makes you think it is not secure?

Adding exception is not possible if the user is a regular user (non admin)

Uncheck "File and Printer Sharing" check box in Windows firewall Exception

or enable "Don't allow exceptions".

The special server (hardware) has been attached between provider's DSL cable

and dsl modem, for interception and recording all voice conversations (and

internet traffic also, seems). One PC have access to that server(probably

some management software installed) for monitoring conversations

periodically. Is there way protect or scramble internet traffic between one

of the rest PCs and WAN? Or not possible, and each packet can be read by

that server?

Is that a VOIP box that allows you to make regular phone calls to any phone?

How do you know the "server" monitors conversations?

What is this "server" you're talking about? Btw, your original post asks a

completely diferent question. Start a new thread if you have a new question.

Go to the switch device (which might be the frontend to a router) and

configure that host (by MAC or IP address) as isolated or inaccessible to

the other hosts. How to do this depends on what switch/router you use. I

used to be able to do this in my old DLink router but not in my Linksys.



On the host that you want to isolate, you could disable the exception in

Windows Firewall that allows the file and printer sharing protocols/ports.

Or you could go into the TCP properties of your LAN connectoid in the

Network applet in Control Panel to disable the File and Printer Sharing

protocol.
