Setting up a home business network for a friend. He's gotten the business class plan from comcast, 5 static public ips. I think we've got the right setup but it's not working. Talking to Comcast and Netgear, they both point to each other as the culprit. Since I've never really set one up myself, I can't decide who to believe though I'm leaning toward not believing comcast based on their past history.
Set the internal IP of the Netgear router (can't remember the model as I sit here now) to 192.168.1.2. Changed the internal IP of the modem (SMC 8014) to 192.168.1.5. Also disabled DHCP on both for now. He's got a seperate home network that is not connected right now in any way to the work network that connects through a router at 192.168.1.1.
Coax comes from teh wall to the modem and the modem is ethernetted to the WAN port of the router. On the router I've set the WAN port to one of the IP's they gave him. Put in the subnet mask (.248) and the DNS comcast provided us. Used the IP block address as the gateway as they said to do.
After having it not work and reading up on it, I've also disabled any settings on the modem have anything to do with firewalling or interferring with traffic. Though Comcast claims it's in bridge mode and none of that should be necessary. The person I spoke with was an utter moron though so who knows. I don't get how they'd KNOW to send it in bridge mode to begin with when they didn't know whether he was planning on using a router or not...? Or are they ALL bridge mode? I dunno and am even more confused after talking to Comcast.
While working with Comcast and Netgear I had laptops connected directly to each device and had static IP'd them both with a gateway of 192.168.1.2 for the one connected to teh router and .5 for the one connected to the modem.
I could get to the internet from the one connected to teh modem but not through the router. Couldn't ping names or IP's. The modem uses an outward facing IP to talk to the web that is DHCP assigned and is completey different than the static IP's we were given.
I was trying to explain this to the netgear guy when he pointed out that I was able to connect to the internet through the modem with teh 192.168.1.30 IP address. He says that means the modem is NOT bridged. I understood what he was saying but I could not get him to understand that there was a public IP on the modem.
Now that may not make any difference, that it has a public IP. And maybe he can tell it's not bridged simply because of that. I just don't know enough about the subject to tell him differently. All I know is that it's not working.
As long as this is, I've probably left out key details. Be glad to provide any further info and thanks for any help, suggestions or ideas that anyone may have!
