Ok, I know we have this thread already, but it's pretty old, and there's a lesser chance anyone will read this there..
I need help with port forwarding.. I got new router and connection, and now my online says I should do the port forwarding.. My connection is now WIRELESS if that makes any difference..
So, I opened my router, and put the values from here:
http://2ksports.com/customerservice/index.php/NBA_2K10 ..
It still doesn't work.. What did I do wrong? Did I miss something perhaps? Please help.. Should I maybe try to open these ports through Windows Firewall?
Here's the picture of my router..

Thanks!
