[PMAC1984]

hey all I was wondering if someone with a clue about the server could help me. The problem Im having is connecting to the Shoutcast server thinger from my server. the error I get is this
[yp_add] yp.shoutcast.com gave error (nak)
[yp_add] yp.shoutcast.com gave extended error (Cannot see your station/computer (IP: it shows one but Im not giving it out) from the Internet, disable Internet Sharing/NAT/firewall/ISP cache (Connection timed out))


What do I Do ?
It also does have my IP number I just put that on there so no one would hack me thanks all
