That wireless 'thing' is indeed your router.

You need to open the ports to allow traffic into your server - as at the moment all traffic is being blocked.
look in your manual to your router and you should be given an IP which will direct you to your webinterface for your router, this allows you to do a number of things including opening ports
you need to find something that will allow you to direct ports or such

Now visit http://www.mohadmin.com/kb/index.php?pa ... 2&id=4&c=3 and open all these ports.

hope this helps
