Title: What ports should I block?
Post by: -ammo- on February 22, 2003, 06:16:26 PM

To better enhance the security of my home network, I want to filter out all the ports that I do not need. I know I need 110, 25, 80, 20, 21, and possible 137-139.  Can I disable the other ports without causing any problems on my network?

if you're not forwarding any ports in your router (or using a dmz host), all ports should appear closed from the internet.  You can check that by using a port scanner on your IP from outside your network.  One easy way to do that is on this (https://grc.com/default.htm) web page.  go to "shields up" then click "test my shields"

That test says that my entire machine is in "stealth mode". I suppose you can't complain about that!
