Dlink 624 Setup

I’ve looked through the posts and couldn’t find an answer to my basic question.

I have a PC (win2K, sp4) connected Dlink 624 that’s connected to my DSL modem. The PC does get internet access no problem.

My question: how do I connect other computers to my Dlink so that they have internet access? I will eventually want to open up my Dlink to provide wireless, but right now i just want to plug some network cables to my laptops running XP and win2K and get them on the internet. Is it a setup on my laptop or is it a setup on the Dlink admin page?

note: i want to be as secure as possible. My laptops have built in network cards.

thank you – again, i searched and either i can’t find it or i don’t know exactly what i’m searching for.
