Hello ! I have seen, it is an english list ! I want to know the differences between a router with NAT, a software firewall and hardware firewall. Maybe one of you have some links to an web-page or article. I read the book "Linux Firewall from R. Ziegler" an therefore I known the strategie of paket-filtering. (a) What is a router with NAT for ? - is there the posibility of dialing in via internet - in which area is a router better / worse than a simple paket-filter SW-firewall with masquerating (NAT) (b) A software firewall (SuSE-firewall) is only a paket-filtering aspect. - what is missing ? is it enough ? (c) what supports a hardware firewall instead of an software firewall ? - why is it better than a software firewall ? (is it really better ?) thanks Harald
