mx vs atv "online bad"

:( :( :( PLEASE, PLEASE HAVE TO DO SOMETHING GOOD FOR SERVICE ONLINE GAME MX VS ATV SLR. FOR ME IS ALMOST IMPOSSIBLE to connect. I ALREADY opened the ports 6000 and U 9103 not working properly. MAYBE YOU CAN SUGGEST ME SOMETHING MORE OR AT LEAST GIVE THE HOPE THAT SOON THERE WILL BE AN UPDATE AND SOLUTION. I also had my ps3 was in DMZ, but the results were not favorable. I also try to Connect the console directly to the cable / DSL modem but I see that it is impossible for the cable type you use. My only hope is to update the game... please help
