Port forwarding failures for a Minecraft server

Problem description: I'm trying to set up a minecraft server for a couple of friends of mine. I can get it to work locally just fine, but it's being incredibly resistant to allowing port 25565 to be forwarded properly. I'm at a loss, since according to my router's firmware, the port is being forwarded. But anyone attempting to connect to it gets a "cannot connect" failure message.

Attempted fixes: I've tried the following:
Following the port-forwarding guide for my router at portforwarding.com
Tried toggling my firewall on and off to see if that was the issue
Tried toggling DMZ
Tried using port scanner at whatsmyip.org to scan 25565. Result always timeout failure.

Just had some port forwarding problems myself. You can get wireshark and tell it to start monitoring your ethernet connection; put in this filter:

You can use something like http://canyouseeme.org/ to send something to the port, and if it a packet shows up in wireshark, it means it's getting thru your router. If there is a reply packet, it means some software is replying. No reply probably means your software firewall is dropping the packet.

Awesome, thanks for the tips. I'll give them a shot.
