Oneeye....I'm doing that same thing on DSL... I registered a name on Register.com and it's costing me $35 a year for everything. The only catch is when my ip changes, I have to go to the website and change my ip in the dns entry. But mine hasn't changed since I got my router...The only downside to your setup is you can't use a router very easily unless your cable modem is external. If you need any advice on any of that stuff, the people in here know what they're doing(and I've had my setup since June). Good luck...I hope find something that suits your needs!
