Reconfigure Comcast Business IP Gateway so can use own router
Posted on 2009-02-19
I currently have a Comcast Business IP Gateway, SMC8014, connected to a switch with multiple PCs. I want to add wireless so I want to add my own wireless router (using a Netgear WPN824). Thus I need to reconfigure the Comcast Cable Modem/Router to act just as a Cable modem. I have accessed the Comcast SMC8014 and have all the current settings. Then I need to configure my router. So here are my questions:
1.) What do I need to all turn off or disable in the Comcast Modem/Router?
2.) What IP address do I need to use to configure my new router? The modem and router each have to have their own IP address correct? I'm assuming I got a Static IP from Comcast, the IP address to access the Comcast Gateway is 10.1.10.1. But what is my static IP (how do I tell)? Which page in the config area do I need to look at, eg. they list under Internet Settings: WAN DHCP IP Address, WAN Internet IP Address, Static IP Block, and under Local Settings: Gateway IP Address, IP Range Start, etc.
3.) What is a public static IP address? They talk about public static routable IP addresses vs. private static IP address.
