    not sure what the issue is, maybe it's just with yours? I used it perfectly fine on my laptop, which has a wireless card in it, and it worked irrespective of whether i plugged it into lan or used wifi. However, it won't work if both are on at the same time, since it doesn't support dual networking. That might be your issue?

    this problem came up on 4 computers i used , if it doesnt support dual networking if you turn wireless off LAN still doesnt work

    might be your router then, because if it doesn't support UPnP (or it might be turned off), then the app won't work

    1) Go to cmd (command prompt) type in ipconfig.
    2) Look for the default gateway , should be something like or something.
    3) Type your default gateway into your address bar.
    4) Login to you router (user, password should be on a sticker on your router)
    5) Go to either the UPnP tab or NAT tab or GameSharing tab
    6) Enable UPnP , save , restart your router and Done
    7) Use the PortMapperSoftware

    upnp is an inbuilt feature in most routers. you can't "download it"
    .NET 4 can be downloaded from microsoft's website. google ".NET 4 download"

    ImminentFate It doesn't display any of my ports and it won't let me foward ports eaither. Could this be my firewall? Heres a picture. I have UPnp enabled and installed the program again. If this won't work can someone direct me to a portfowarding tool that works?
  25. Offline


    It doesn't show you your ports because normally you don't have any upnp ports. UPnP ports close when you restart the computer, usually - so most of your ports tend to be saved into the router, and those don't come up here. What you can do is add your minecraft ports to this, and they will stay until you restart your computer. This tool is more for those who can't forward from their router

    It also says the specified details aren't workingor whatever when I try to foward Minecraft. This tool has worked great for me in the past as in like 3 days ago. I had to set my firewall settings back to default to fix some internet issues and now it doesn't work. I really need to foward Votifier because my server is already up. It's a really nice tool to have all your ports easily accesible like Port Map for windows. I hope you can help me get it to work again.

    Uh ok so how do I fix this?

    so it was working before? interesting, try disabling your firewall (temporarily) and see if it works then. if it does, re-enable your firewall, but add the program to the exceptions list. Just ask if you need help with that

    The firewall and the restart did it, but now I need to go about figuring out how to get it to work. Thanks for your support and great application. :) But now how could I make it so it will work with my firewall on?

    try adding the program to the "allowed" list on your firewall. This can be done by going to the control panel, hitting "windows firewall" and then in the sidebar (if on windows 7 or vista, not sure where on xp) clicking on "allow a program or feature through the firewall".
    Add the Port Mapper, you will have to click the button that says "Allow another program..."
    When done, try again, you may or may not need to restart your computer for it to work

    Ok so I downloaded your program months ago and it worked great I loved it no more shitty port forward crap no matter where I went I could host my server. but I moved to my new house and I have the same router same internet provider but it does not seem to be working why would that be?
