vmware sever 1.04

Hi guys I need help here i am new to linux, i got centos 5 and virtualmin installed nicely into my win 2003 host using vmware server, i can log on to virtualmin local, using 127.0.0.1 or the real ip, and even the domain name, but only inside the guest windows. From the outside the internet i get timeout and the dns settings i have resolves to the correct ip. can you guys help me configure the settings, so i can get the server from the net.
