TECH Port forwarding question.

[Repentinus]

I'm currently using a DLink DIR-655 router and am having trouble with my port forwarding. First, note that I have done this a million times successfully in the past. I can access my router's webpage and get to the portion to enter in the information for port forwarding. I can even input said information and save. This requires a reboot and in the past that was that. But now even after having done all this, when I check http://canyouseeme.org it says the ports I've open are still closed.

I've tried to use multiple entries of different ports and also tried to open a range of ports to no avail.

Any help at all would be appreciated!

What ports are you trying to open exactly..?

 

[Repentinus]

Any ports. I use a program that benefits from using an open port. Another weird thing is that I've had ports that were open that mysteriously closed themselves. I used to have a range of ports in the high 6000s and also some in the 25000 area. But not any more.

You dont have a software firewall blocking them?

What program is this?
Is it running when you test to see if the port is open? Even if the everything is set correctly, if the program isn't running then site like that will see it as closed.

A simple one to try to make sure you at least have the router set correctly that I use is uTorrent.
You can set the port in it to anything you want.

There's also a program you can get from a website called simpleportforwarding.com that attempts to handle it all for you.

That must try to use UPNP... which is hit and miss at best.

No it's not using upnp or no it's not hit and miss at times??

 

[CodeX]

No.

Look, I've written applications that attempt to communicate with the router and setup port forwarding... so if there is a way to do this reliably with any generic router other than UPnP I would love to know about it...
