>I have a cable modem and a Linksys BEFSR81 Etherfast Cable/DSL Router. The cable modem resets the IP address every 24 hours. The Linksys is being used as a DHCP server for the local network. I have Norton Virus protection on each of the computers (5 of them) on the local network. Is this reasonably sufficient protection or should I be looking for a firewall device to put between the cable modem and the Linksys router?
