There are other intrusions that fly right by a firewall and infect the machines. Look up "drive by downloaders" as an example. This is why we install protection on each machine.
i'm working on upgrading my network from 10mb half-duplex to 100mb full-duplex.
I've got a spare computer and a spare network port.
I want to set this computer up as a firewall to protect my network of 6 computers from outside intrusions.
I'm thinking about running the internet connection thru the computer and then distribute it to the network. The program i want to use is comodo firewall. Will it do a sufficient job of blocking unwanted crap from entering my network?
