I tried out the Verizon 4G USB card and it was awesome - 16 to 20Mbps download and up to 3Mbps up. I would like to use this as a backup for one of my remote sites in case their Internet goes down. How can I take a Window 7 machine and have it serve as a router, NAT device and firewall so as to share that 4G USB card with the rest of the devices on the LAN? I would go Linux but I don't know of any Linux software for this yet. And I know of no specific 4G network specific devices yet. Anyhow I would like to know how to do this with a Win device. Thanks.
