How to configure Windows Firewall with an
Exception
Let's
say you have a home network and you want to allow one or more of the
computers on the network to access files, but you don't want all the
computers on the network to be able to do so. Setting user account
permissions on the files and folders won't work if it's connections from
specific computers, rather than specific users, that you want to block.
However, you can use the Windows Firewall to do it. Here's how:
- Click Start | Control Panel | Security Center.
- Select Windows Firewall.
- Click the Exceptions tab.
- Check the box for File and Printer Sharing. At this point, by
default all the computers on the subnet will be able to access the
file shares.
- With File and Printer Sharing highlighted, click the Edit
button.
- For the associated ports, click the Change Scope button.
- Click the Custom List button.
- Enter the IP address(es) of the computer(s) that you want to allow
access.
- Click OK.
Note that you can also use this feature to allow access to all
computers, even those on the Internet (NOT recommended).
