I don't know what the problem is. If you have the router configured properly with the correct ports and IP addresses, it should work. If it doesn't work, there is a problem with the router or you have something else blocking you.
Does this help at all?
Are you able to connect to other JJ2 servers properly? (Not your friend's)
