I have a mac pro with 2 network cards. I have a modem with ONE ethernet out. I need a router, in order for my TiVo to be online constantly/whenever it desires to check for program info (I do not have a landline). I do not want to buy a router. I have heard that I can somehow rig my MP to act as a router. Is this true, and if so, how do I do it? Googling reveals nothing of use, searching here reveals nothing of use. Please help before I kill myself or my cat or possibly do some sort of joint massacre in honour of Hale-Bopp.
