    Cannot use or see any open ports?


    I'm trying to use port forwarding 51234 so that I can host a server on MapTool, but nothing I do seems to work.I've added port 51234 as an exception both in my router's port forwarding settings, AND in Windows Defender Firewall, but I can't get anyone to connect; everyone gets a "timed out" message. I've been trying to use canyouseeme.org, which cannot see 51234 or in fact ANY ports that I put in. I've tried turning my firewall on and off, and that hasn't changed anything either.I put in "netstat -ab" in my command prompts to bring up my ports, and 51234 does not even appear on the list. I a

    Click next/OK as required to complete installation. Repeat the steps for all Intel USB devices. Finally click on each USB root device and press DEL to delete it, reply YES when asked. After deleting all USB root devices restart the computer.

    I hope this is detailed enough...

    Port is being blocked

    Hi,



    Thank you for writing to Microsoft Community forums.



    • Are you aware of any changes that happened on the computer prior to this issue?


    Upon researching, this seems like an issue due to the port scan. You may want to try the steps listed below and check if it works.

    • Login to your Netgear
      NX6200 Extender GUI      .
    • Click on Advanced tab and choose
      WAN Setup      .
    • Check the box for Disable Port Scan and DoS Protection.
    • Allow it to update and check if the port is still being blocked.


    However, if the issue persists, I suggest you to post your query in the
    TechNet Forums, where we have support professionals
    equipped with knowledge on port forwarding.



    Regards,

    ISP Blocking Port Forwarding Conspiracy???

    I've come across a few posts that suggest that some cannot open/forward ports from their modem. It's been suggested that it's a direct result of ISPs trying to crack down on torrenting. However, I am not sure how true this is. Is there a way to test this? Is there a way to see if a port is forward on your modem if it's open or not?
