Question please help my friends cant join my server!

my servers up when I run the command prompt to load all the plugins and such and it works. I can play on it with all the plugins. but my friends cant joim. I know its port forwarded right because it wouldn't of create the server if it wasent. I have went int my router and computer firewall and disabled anything stopping tcp or udp to go through port 25565 but still the same problem occurs. they've tried all the ip's ive had to join. lke my ipv4 ip my default gateway ip the one in my server properties file nothing is working please help weve run out of ideas.

 

@timtower i just did an open port checker and it says he ports closed.. How could this be i port forwarded right

 

Another explanation could be the Firewall, sometimes there is another setting in the Firewall which needs disabling, In my experience it was called 'IP Flood Detection' once this was turned off it worked fine, maybe look for a similar setting.
