This is my current setup: SMC8013WG-CCR Cable Modem/Router/Firewall Fedora Core 4 with ISPConfig Installed Macintosh OS 9 Mail Server (using NAT) 5 Static IP Addresses from my ISP I want to setup my fedora server to use one of the Static IP Addresses supplied by my ISP. I want to eventually get rid of the Macintosh OS 9 Mail Server (old) and use the Fedora Core 4 Server only to handle Web/FTP/mySQL/DNS/Mail serving duties. However, I don't know exactly how to setup the IP addresses so that the server can be accessed from within the network and from outside of the network. If anyone has any suggestions or any howto's I can read, please help me! Thank you!
