I use the Windows 7 firewall, could that be it ?, the support for windows 7 is over
No. There should be nothing wrong with that firewall. When I said you might have another firewall, I meant there might be a second firewall installed. For example, if you have a security suite or something like that, it might have it's own firewall that you'll need to open the ports in as well.

"DHCP Enabled": That shows that you're not using a static IP.

I don't think that's the cause of the problem you're having though. But if you find a solution that requires you to have a static local IP, you'll need to fix that.

And just to be clear, you would disable DHCP in your computer's network adapter IPv4 settings. (Leave DHCP enabled on your router)
