You mentioned Verizon. It was my understanding that all DSL customers had been converted to FIOS, and if so, you do not have a cable modem in your house, you have a router. FIOS logically terminates at the ONT on the side of the house, they can run coax or CAT5E into the house from there. Updating to a newer Verizon-supplied router with better throughput and gigabit support may be a phone call away, and low or no cost.

What do you think about using a COTS wireless router with gigabit
ethernet as a firewall? All I need is NAT provided by the router. I'd
disable the wireless, and NAT would insulate the local net from the
internet. I'd plug the "WAN" plug into the verizon-supplied cable
modem. Most wireless routers have 4 gigabit ports, although I'd only
need 1 of them. The old router would provide dhcp addresses on the
local net.

Do you think this would be robust enough to provide thruput on par with
the low cost commercial routers already mentioned by others on this list?
