Not really a security issue but I could use some help. I am currently running (3) Win98SE machines off of a Linksys Cable/DSL router, tied into a cable modem. My oldest son in his infinite wisdom, and in an obvious move to complicate my life as much as possible, bought a Mac G3 running OS 9.1. From what little I know about Macs, they seem to have migrated to TCP/IP with their more recent OS's. Will I be able to just Cat5 out of his NIC and configure his machine normally? My ISP currently assigns IP's automatically and I have set up the router as a DHCP server. Any input or a heads up about possible conflicts would be greatly appreciated.
