Hello

Hope this is the right section in the forums for this question. If not please tell me in which section I should post this question.

I want to connect a PC (PC#2) on a home network. I want this PC#2 to access any other PC on the network and I would like any other PC to access it. This PC#2 will probably run Windows XP.

The PC (PC#1) that will connect to the ADSL router and the internet will run Windows 8.1.

Is it possible to block PC#2 from accessing the internet completely. That is all inbound and outbound communication?

Where would one implement such blocking/filtering and how? On PC#1, PC#2 or on the ADSL Router.

Thanks for the help

The easiest will be to start at the routers' firewall.
 
If you are going to use the LAN ports on the back of the DSL router to connect the PC's on your home network, then it will change things.

Check you DSL router settings if it has MAC address filtering, which it should have. That is how you'll control access to the internet, by allowing only the one PC's MAC to verify that it has access to the internet.

Then, share the folders on the PC's. The only problem with a mixed home network, using XP and Win8/7, is that XP doesn't have home group. So the password won't work. You will have to enable sharing on folders and share it with Everyone, not a specific user. Do this by right-clicking on the folders as per usual and select share.

The DSL router should be doing DHCP to assign your PC's with IP's, so you won't need to set them manually.
 
You router should allow you to block internet access to a specific user/group/port etc. although that functionality might not always be available on all routers out there. There are a few client-side tricks one can use to "block" internet access depending on what your intentions are. Why do you want to kill access to the XP PC#2?

Or simply set a non-existent gateway in IP settings for the network adapter. Rude and crude, quick and easy.

He said in and out. Doing it your way the PC would still be able to receive data from the net

Block at router level!
 
Of course. But I get the sense the OP doesn't know much about routers. Also, you can't navigate to a site without at least sending a REQ. Seems he wants to stop young kids from surfing the net, but allow access to the Homework Server.

On some routers blocking MAC addresses also block connection to the router.
 
For performance reasons I don't run anti virus software on my main PC. My internet browsing runs on a VM with the antivirus and additional firewall that keeps it from the other machines in the network.

I filter the MAC address on the router and it has been fine for 6 years plus.
 
WILL ALL THE PREVIOUS POSTERS SEE THIS REPLY?

I like your solution. I have a DLINK 2650 router. http://www.netcheif.com/downloads/DSL-2650U-UG.pdf
This router does have MAC address filtering. See page 56. I know how to get my PC's MAC address. "ipconfig /all"
and I am sure you are all laughing right now. Yes I am a novice. I will also be able to find my way to the
page on the modem.

One thing that I have read is that some programs use tunnels, port forwarding and all kinds of strange mechanisms
to connect to remote servers. I do not exactly understand this. I am mainly trying to give the kids a PC that they can use without supervision.
I also have a capped acount and I think it should be easier if I can just block ALL access to the internet.
That includes all background communication that could be going on to prevent the consistent updating of SW.
It will be easier for me to do this than to go and look for all the settings to switch off automatic updates and
to remeber to do it everytime I install something. Save a bit on the data bundle.. if that is teh right term.

@Garyvdh
I think I will be able to do it if pointed in the right direction. Have being fiddling enough to do some basic things.

Thanks a lot for the help so far.

This is a great forum.
 
Why not install something like K9 on the other computers, you setup the filters on the service, and it blocks anything/everything on that list, Perfect for kids.

Trust me it cannot be uninstalled or bypassed without the password, i forgot my password, it was a BTICH to remove.

Yes one could do that but then you would still have upload/download data that other application can initiate on the machine so I would still not be able to optimize my Capped account usage.

Look in the end I will have to be practical. If doing the MAC address filtering is going to be to much of an issue I will have to install one of these "k9" type programs. I will be getting a second hand PC this weekend then I will try the MAC filtering on the ADSL router. I will also have to read a bit more about these tunneling/port forwarding thingy. Maybe I get to understand it a bit more.

Thanks
 
I cant say for sure, but im pretty sure you can block most things, p2p, streaming media, install the app and test as see if it works for you.
If its kids and they dont know how a computer works, just enable the proxy on IE and type in random stuff.
