	Port Mapper is a freeware tool which helps home users open/close ports in their routers and gateways securely. It automatically maps and manages ports in the router, enabling online multiplayer game play without disturbing the gaming session. Port Mapper is more secure than manually opening and closing ports, because it opens the ports only when needed and automatically closes them when you are finished playing. Port Mapper works with your Internet gateway/router in such a way that you can have control on the programs that communicate over your network. Using Port Mapper, you can expose applications to your friends over the internet in a safe manner. It also supports wireless connectivity and notifies you when you go out of range of the gateway. If you are a gaming freak who loves gaming on the internet and don't want to be disturbed with the manual opening and closing of ports at your router, you are sure gonna love this tiny tool.

	COM Port Stress Test  License: Freeware
	When creating an application that actively communicates with external devices through COM or RS232 ports, the developer must make sure that the ports will be able to handle any data flow without producing errors and locking up the system. This becomes especially important when it comes to surveillance and alarm systems, industrial controllers, medical solutions and other areas of application where data integrity and system stability are crucial factors. If you are puzzled by having to stress-test COM/RS232 ports and see no easy way to do that, make sure you don't miss COM Port Stress Test, as it does exactly what you need! COM Port Stress Test is a compact and affordable tool for testing COM, RS232 and RS485 (with converter) ports that generates a stream of data with random communication settings. Stress testing places great emphasis on producing excessive load of varying intensity on communication ports, which guarantees that if testing is successful, the application will operate properly under normal circumstances. Developers and hardware engineers will appreciate the ability of this software to test communication ports (including virtual and USB serial ports) at their maximal bandwidth and simulate the harshest operational conditions possible by generating an extremely fast data stream with alternating baud rate, flow control, RTS and DTR states. Which is more, COM Port Stress Test is capable of working with two ports at the same time, so you can actually use it to test null-modem cables. Connection speed and the amount of data sent to the ports are shown in the program window. The bottom line is quite simple - our software will help you push your communication ports to the limit. Knowing that your customers' systems are operating without errors or lock-ups is a great thing. Try COM Port Stress Test and rest assured that you've done everything to ensure the stability and rock-stable operation of your product under the most complex and conditions!

	Emsa Port Blocker  License: Freeware
	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.
