Finally, dudes you are GOLD! (Stephen Coy and Tan Mariani) :^0
It is a combination of both your answers, I tryed changing the IP in the jndi.properties file a week ago but it didnt work, because I was starting the server with -b 0.0.0.0.
Now when Stephen Coy pointed me in that direction again I started experimenting and when I tryed Tan Mariani 's idea of starting the server with -b 192.168.6.100 it worked.
And you were right I shouldn't have cared about the port.
Now I don'y know to who should I give the corect answer, I'll leave that up to you!
Thank you dudes, you saved me tons of headaches.
