How to Block Incoming Attacks Without A Firewall

Limit your exposure to attacks from the cyber world by blocking incoming connections. Go to Start > Settings > Control Panel > Network Connections. Right click on ‘Local Area Network’ and go to ‘Properties’.

 

In the scroll box, click on ‘Internet Protocol (IP/TCP)’ and then click ‘Properties’; in the new window, click ‘Advanced’.

 

Then in the other new window go to the ‘Options’ tab, click on ‘TCP/IP Filtering’ and hit ‘Properties’. Uncheck ‘Enable TCP/IP filtering (all adapters)’.

 

Next, in the above ‘TCP Ports’, check the radio button that reads ‘Permit Only’, and then add in the ports you want people to be able to access.

This way, you close the ports you don’t need. An alternative to this tweak could be running a firewall or enabling Windows’ inbuilt firewall.

 

A point to note is that in order for other computers to connect to you, like using Windows Messenger to send a file, you’ll have to make sure the required port is not blocked on your system.

But hey guys, Commodo firewall is free and is  very best. Use it to avoid all worries.
