Howdy folks,

 

I simply cannot get any ports to appear open on something like http://www.canyouseeme.org/.

 

  • My computer ipv4 is 192.168.0.25 as shown in ipconfig /all
  • I set up some forwarded ports to that IP following the guide at https://portforward.com/technicolor/tc7210.dnz/
  • http://www.canyouseeme.org/ then shows none of those ports as open
  • I then turned off windows firewall, defender, turned off wan blocking in the router (not sure if any of these are necessary but did so anyway) - still no ports open
  • Next I set my computer IP as a DMZ Host in the router settings and rebooted - still no ports appear  open
  • Next I called vodafone and they advised that they cannot help with port forwarding and to just google it - it seems there is not much info out there for this router.

So basically none of my ports are open according to http://www.canyouseeme.org/ or similar, and no one at vodafone can help allegedly - does anyone know how I can resolve this?

 

 

 

Thanks in advance!

You do realise they're only "open" when there's a program/service listening on that port? I just want to be clear.

 

So for example, if you hosted a webserver on port 80, DMZ'd it. Then it'll say the port is open, and someone else may access it.

Is the testing service checking the right IP address? I have had one that was confused with a transparent proxy and was trying to test the IP the proxy used not the one from the forwarded for header.

What happens when you actually try and access the service remotely? Depending on what you're port forwarding to there is no guarantee an open port checking app will be 100% accurate

No, no I did not know that. I'm trying to forward ports for a steam game, but I guess I can't test it until I'm in the middle of the game. Thanks for the heads up, hopefully that's the problem.

From vague memory you might also need to turn the firewall down to Low to allow any traffic through ports that you've set up.
