We have several small offices with 3 to 6 computers. They have DSL modems and Linksys routers. The routers are the basic model (BEFSR41) and not the model that says it has a firewall (BEFSX41). However, on the Linksys website it says the BEFSR41 has built-in Nat technology that acts as a firewall and protects the internal network. I know what NAT is but wonder if it is enough to protect the internal network from hackers and the Blaster worm going around.
