thank you for your reply, Public or Real IP address is a known and unique IP address given to your DSL modem when connected, and in other words, your Modem is in the front line to the World (Internet), but in my case, i'm with cable guy who give us Private IPs, So my question is, is there any chance to play PS3 online with private IP ??
