[Release] PortMapper - A Port Mapping Utility

[Jash]

Port Mapping (A.K.A Port Forwarding) is an essential step for servers who wish to allow clients to communicate with them through certain ports. However, some servers often have trouble accessing the router either due to lack of router credentials or lack of knowledge.

Today, I present to you a utility that helps to:
1) Create port mappings (I.E. port forward)
2) Remove port mappings (I.E. un-port forward)
3) View all current port mappings
4) Edit current port mappings
All WITHOUT the need for router credentials. Yes, this means you wont have to login to your router to use this utility, neither do you have to know the username or password for your router to use this utility.

1Q) What is "InternalClient"?
1A) It is the local IP address the router transfers incoming connection to. For example, 192.168.1.101, 192.168.1.231

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
