A BT Openworld router-- help!

[CaitlynDaFox]

So I'm getting that good old "[yp_add] yp.shoutcast.com gave extended error (Cannot see your station/computer (IP: xxx.xxx.xxx.xxx:xxxx) from the Internet, disable NAT/firewall/ISP cache (Connection timed out)" message.

The deal is, another computer in this house runs a broadband network for us (he's the central computer), so I'm simply partaking in the experience. However, I've tried my computer AND his to figure out where the heck to access router settings, and I've come up totally blank. In fact, in one help file, it said router settings could NOT be changed for some reason or another.

I'm not running a firewall, I don't think there's anything else that could be wrong. I just -know- it's the router.

So-- well-- let's just say I'm VERY confused. Is there anything I -can- do? HEEEE-AAAALP!
