It is possible. It depends on whether your modem can accept multiple connections. In other words, some modems are simply point-to-point and some have a router built in. If you have a point-to-point modem, no adding a switch won't work. That's why I recommended the D-Link unit. It has everything you could want in a single box (modem, router, firewall, switch, DHCP server and wireless access point). ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - Time: Nature's way of keeping everything from happening at once. - ---------------------------------------------------------------------- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
