Application Port Mapper - The Easy Way To Forward Ports

Overview:
This tool will let you forward ports without requiring access to a router, provided your router supports UPnP. Most modern routers do support this, so it should not be an issue for most.
The tool does not only have to be used for Minecraft/Bukkit. It can be used to forward ports for any game or software program.

Download:
Download the Port Mapping Tool on Google Drive
REQUIRES .NET 4
How to Use:
The tool was designed to be easy to use, so there isn't any complicated terminology in it. To forward a port, all you have to do is specify the type of port (protocol) , the port number, and add a name.

The program will show currently open ports, and the example shows the information required to forward Minecraft or CraftBukkit through the router. To remove an assignment, simply right click it, and select "Remove Port Mapping"

Note, however, that if your firewall prevents Java (or the program that needs access to the port) from accessing the internet, you will need to allow it through the firewall for this to work. That also applies if you are opening ports manually.
Also, depending on your router, you may have to re-open the port after a period of time.

Planned Features:

• Adding a range of ports
• Allow the program to make a firewall exception for the program you want to forward
• Editing of a map without having to delete it first.

This is going to help a lot of people
Firewall would be tricky though, as lots of people aren't using different firewalls.
(Now I have something to redirect people with port forwarding issues to )

Only issue I experienced while testing is that I had to remove the created port twice.
I added the port, then I clicked remove, and while the list refreshed it was still there.
The second time it was removed.
I'd also mention the delete function somewhere in the program
How does it react if a router doesn't support uPnP?

Having a problem using this, whenever I put in the information to forward a port, I get "The specified details are not valid".

I chose the protocol, port and put in a description, I added it to my allow list for my firewall, ran it as administrator, and still no luck.

Here is what im entering in:

i am having the same problem as well

Mac?

Does your router support UPnP?
Works fine for me. I run windows 7, I'm administrator on my computer but didn't click "run as administrator".
You need .NET4, btw.

@ImminentFate:
Maybe add the .NET 4 requirement in the OP, with a link to the download page for .NET?

You could try running it using mono.

Working for me...Good job!

i am not sure if my router can run UPNP, how do i figure that out?

Yeah, I have UPnP enabled and .NET 4 installed, checked and working, far as I can tell.

(Incase I did indeed do something wrong, here are my router options for UPnP:

I would recommended to you portforward.com. Once there, go to routers, find your router, and then somewhere you should be able to find where you can get into your router to enable UPnP if it is disabled.

To find out how to get in, try selecting any application from the list once you find your router then just follow the steps up until you have logged into your router. Hope this helps.

@ImminentFate Not working for me either, says "The specified details are not vaild", and I clearly have UPnP enabled.

http://forums.bukkit.org/members/imminentfate.93515/ May I have the sourcecode? What language is it written in? I may be able to make a Mac version.

It does remove the map the first time, it just takes time for the signal to go to the router.
I know upnp may be an issue, but in today's day and age most routers have it

It's written in .net, and hooks into the windows networking API. So I'm not sure you could convert it to Mac

Okay... Ill see if I can do it another way

Yeah, sorry I couldn't help, but try looking for a suitable network library in Mac to hook into with your coding, and it may be easier.

Okay! Lol I thought I found something, but I accidentally ended up making my computer a router...

bahahahaha

Not funny^.^

What is port mapper even supposed to do? See my problem was that no one can join my hamachi server other than me and they are connected to my network but they STILL can't join. I was recommended POrt Mapper but I have no idea what the heck it is

It's for port forwarding, so that you don't need to use hamachi. Have a look at my port forwarding / hamachi tutorial if you need help.

I use "Port Map" on mac, works great, Here's a link

Thank you so much I may be able to make an automatic port forewarder for Mac!

I put in exactly the same details as you but it says, 'The specified details are not valid.' Any help would be great, thanks.

Your router probably doesn't support upnp, or it's disabled. Check your router settings.

To be honest, I don't actually know where to find the settings. I also tried to follow the manual instructions, 'You will need to allow connection to the port 25565. This can be found under "Services", "Ports", or whatever your router calls the setting.' But I couldn't find 'Ports'. And thanks for the reply, I usually don't get one

And when you guys talk about a router, do you mean a router or a modem, because I don't have a router?

If you don't have a router then I think you have bigger issues...

Why? Everyone in my house connects straight to the modem, we don't need a router.

But doesn't a router just make it possible to add more devices to your internet, or to your modem?
According to my brother a modem can be classified as a router as well as a modem so that might help.
