Hi,
I have a small peer to peer network with 5 computers. One computer with XP is connected to dsl modem and linksys router. The other four share Internet connection via that computer. All have NAV. We want to add a firewall, do we need to just put the firewall on the computer that is connected to router and dsk modem or do we need to put firewalls on all five computers. We do not have a lot of money. thank you for any help
