What model is it? If you're connected directly to a modem with no router involved, then there are no ports to open.

My Comcast modem is -----------------> RCA model DCM425C

I 'm connecting with router -----------------> belking N series model F5D8233 - V4.3

Thank you

So then you mean to ask how to open a port on a Belkin Router.
