=======================
Emsa Port Blocker is a TCP blocking utility. What it does, is blocking
unwanted tcp access from/to your computer. It is not a firewall, but up
to some extent it could be regarded as a similar tool. Its purpose is to
prohibit TCP access on certain ports and ip addresses. IT can also be
used as a TCP monitor because it shows TCP connections currently active
on the machine.
This program works two ways. It can be configured to block access to
certain local ports, but it can also prohibit access to specified remote
ports as well. For example, you may try adding the port '80' to remote
blocked ports. You'll immediately notice that you have disabled your
browser's capability from accessing the www. You can use this program to
block unauthorized access to certain ports on your computer, for example
network ports like TCP 135 or 139 and so on. You can also use the
configuration to permit connections between local IP's, or block even
those as desired. The program comes with a function allowing to detect
local ip's and adding them to the 'allowed' IP list.
