Hi,


To play online, NBA Live clients need the following ports opened:


HTTP 80 (inbound)
HTTPS 443 (inbound)
MsgConn 13500 (inbound)
Roomsvr 20901-21000 (inbound)
Dynamic 32768-65535 (inbound and outbound)


Please let us know if we can be of service in the future. Thanks,

Is necessari to open all the ports in the interval for it to work? Or just maybe 20 or 30? This because I've a shitty router whose config program could open only a port at once, and tne the process to open 20.000 would be long...

Thanks

Does your router have the option to make one PC the so-called "DMZ"? That makes the router forward everything to this PC.

Sadly no.. it's a really basic router, it works well but it's an hassle to configure. Did anyone with a router knows the minimum ports required to be open to allow ip 2 ip play?

Thanks
