I made the mistake of opting for the internal DSL modem with my new service. But now I have researched home networking, and I want to use something like the Linksys EtherFast DSL router/switch. The internal DSL modem does NOT act as a NIC. It just has RJ-11 jacks for the line/phone like an analog modem.
So, how can I take advantage a router's firewall and DHCP services for internet sharing between NT and Linux when the internet connection is going straight into the NT box? One concept I've heard is to route the internet connection out one NIC to the router and then back to each node. Thus the box with the modem would have 2 NIC's. Of course, I have no idea how to implement this.
