Antrix 2.1.0 Server, Need help making it live!

ok, i've managed to make this work on my own computer and now i want to share it with friends, i've Downloaded a program called ''Hamachi'' for small online networds of groups of friends to give me an IP i can use,

So i know i set the realm.conf address to my External ip, (which is currently the one from hamachi), and nobody who uses this same IP in they're Wtf file can connect, i've searched all the posts i can find here, including the hosting for dummies (and now consider myself less than a dummy) but is there more i still need to do?

this is a Routered machine, connected to the router Wirlesley, is this going to makea difference?

please let me know with any advice you have, it will be hugley appreciated.

(i've already disabled windows firewall, and the router one,)
