When using Public IP addresses on one interface, usually facing your ISP, and using Private IP addresses (AKA RFC 1918) on another interface, usually facing your LAN, one needs to utilize network address translation (NAT) in order to connect LAN computing resources to the Internet.
Cisco has a fantastic article on how to perform the necessary procedures on their web site.
