If you can use that public ip for just the webserver and nothing else then a standard static would do.
However if you want to prepare for expansion later, you would need to utilise port forwarding, so you would set it up to forward any port 80 traffic to the privately addressed inside ip address. This is by far the recommended way.
I've been trying to do a similar port forward, however have been unsuccessful. My outside address is obtained from my ISP's dhcp and is not static. This is from a cable modem connection, residential service.
I'm trying to effectively do what standard home retail routers like Linksys or any others do.
Is this possible over a DHCP'd single address service?
