NAK error help...
 

So everything seems to be working good, although I am getting a nak error:

<04/04/08@16:16:34> [yp_add] yp.shoutcast.com gave extended error (Cannot see your station/computer (IP: 72.140.210.220:9000) from the Internet, disable Internet Sharing/NAT/firewall/ISP cache (Connection timed out).)

I am running on just a modem so I believe all my ports are open. Firewall is disabled. Whats the problem?

Also, what is ISP cache, NAT, and internet sharing? Perhaps my problem could lie in one of those.

your modem most likely has a built in firewall. Check out www.portforward.com to learn how to configure it.

Also, software can act as a firewall ... windows firewall, zone alarm, nis are all examples of this.
