I have a L It is my understanding that the Linksys router-firewall will prevent outsiders from getting into our small net, but I don't know what further protection, is afforded by installing something like Smoothwall, or another "true" hardware firewall.
I do know that Smoothwall would provide much more information about attempted intrusions etc., but that would not be the same as added protection.
Installing Smoothwall, or some such, would be cheap, easy, and might be interesting.
Only I can decide if that might be worth doing, and in order to make that decision ask what additional protection would I actually be getting.
Very sincere thanks,
