if i have IPCop on a computer that is wirelessly connected to the internet and i have 2 ethernet cards in it, would i be able to hook that computer up to another directly by ethernet cable or would i need something such as a linksys wired router? if i do need something in between the computers, what would it be?
I dont believe so but it depends on what you are trying to do with the other computer. If you are trying to share the internet I would recommend the other router. Other wise you could set up an ad-hoc network if you get you a wireless card
Shouldn't be a problem to plug in another computer in the eth card and establish the routing. I know how to get this done on a plain Linux box - but I'm confident this also can be configured on a IPCop box.
