I'm running a Windows Server 2008 system, and Apache opened the necessary port itself on the servers software firewall. If it doesn't, try to find the firewall settings in the system settings, its quite easy, iirc.
Most routers have an easy to configure web-based interface. Have you tried to enter your routers IP in your browser window? If that doesn't work, check for the manufacturers manual, its function i'm almost certain every modern router has.
Keywords should be something like port forward.
Be sure to open only the ports you really need! As a dynamic DNS-Provider, I use dyndns.org, and have made quite good experiences so far - even though the services I use are free.
