Re: Resurrect an old PC as a firewall?
Well, if you are trying to protect other PCs on your LAN from outside attacks, then yes, you would need 2 NICs in the firewall/Router PC. One connecting to the modem, the other to the lan. (probably to a switch that the other PCs plug in to)
And I think the big difference between a firewall and a router is that the router is able to block incoming traffic only as a bonus. Network Address Translation is used, so the incoming data doesn't know where to go when it hits the router. outbound data still flows freely. A firewall processes the data coming in, to varying degrees based on software/hardware. They also allow outbound traffic limiting.
