Emsa Port Blocker
-
Version
1.0.15
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.
Functions:
- When first started up, the program shows a list of
TCP connections on your machine.If you don't see
anything there, try opening browser and visit some
site and you'll see them.
- By unchecking the 'Show only connected' checkbox the
program will also show tcp connections in other
states, like LISTENING and so on.
- The left hand list is versatile and its meaning
depends on the last button clicked - check the label
above
to see what the list is currently displaying.
- To add items to a list, type into the textbox below
and click on add. Make sure you enter valid data
(valid ip addresses/ valid port numbers).To delete one
item, select it in the list and click on 'Delete'.
- To view Allowed IP Addresses, click on the
corresponding button. By default, here you will see
your local IP address (127.0.0.1). You may want to add
all your local IP addresses to the allowed list.
This program is Freeware.
