Jazz Jackrabbit 2 Online

hello

I connect with my computer(win vista) to a DSL Router. I had open the ports 10052- 10060 TCPand 10052 UPD by the router and i had open it too in the windows firewall. I can see and load the inforamtions in the "game in progress" windows but nobody can connect to my server. ( i see only the numbers in the list without name and the players connect not full) i had try it wiht jj2 1.23, jjm ( 1.23) and 1.24.

(only join games works great)

can somebody help me?

thanks
