SMCD3G-CCR settings with static IP and my own router

I mistakenly did a factory default reset on my SMCD3G which has firmware 1.4.0.49.7-CCR. I DO have "Disable all rules and allow all inbound traffic through" checked as well as "Disable Firewall for True Static IP Subnet Only" and "Disable Gateway Smart Packet Detection". The WAN settings of the Linksys RVS4000 router are set according to the Static IP sheet from Comcast (and have not been changed since installation two years ago), and its WAN port is connected to one of the SMC's LAN ports. So here's the problem: with the SMC's LAN set to its default 10.1.10.1, you can't get to the internet through the router, and the Intrusion Protection Service on the Linksys light flashes. BUT, if I set the SMC's LAN IP address to the static IP gateway address (not what you're supposed to do), the internet becomes accessible from behind the router. However, the whatsmyip.org ip address is the SMC's WAN DHCP IP Address, not the Static IP address, so I doubt external access to the static ip will work. So what else got erased when I did the factory default reset?

What prompted the fiddling? We have the Deluxe service, 50 down, 10 up, but we're only getting about 2 down most of the time.

Since Comcast Business Class service doesn't operate on weekends (but businesses do), I need help! Thanks!!

The configuration that Comcast uploaded to the modem when they "provisioned it". Gonna have to call them up and have them reprovision it. You'll want to get the MAC address handy..to read to them, so they can find it and upload the config file. Should be a couple of them on tear off stickers....they came in the box, the tech that installed it should have affixed it to your account sheet he left in the box and stuck one on the bottom of the SMC.

Damnation. They're coming in the morning. I guess I'll need to put warnings over the reset button, or relabel it "Bork My Modem."

One thing though, in the Gateway Summary, one of the Initialization Procedures is "Download CM Configuration File," and it says "Complete." I wonder what that means?

Regarding the MAC address, the WAN and RF (or Gateway) MAC addresses on the SMC's bottom label do match the ones shown in Gateway Summary/Network. There's also a second label on the top of the SMC with just the RF MAC and serial number.
