What about malware coming in from email / HTTP / - Backdoors or blended threats 
that arrive via the affore mentioned means, they then open up Reverse 
conenctions out through your unprotected network [If a Firewall was in evidence 
then you would state which rules and which sockets were allowed out] You would 
also implement Personal Firewalls as well on each client

Surley a Firewall is more than just protecting connections into your LAN?

Just my opionion anyway

Hello,

does anybody know a good and secure Setup for a CISCO 836 integrated firewall? 
As of my knowledge, I dont need a firewall, when using dynamic nat. All PCs use 
one ip to the internet, and no global to local IP mappings were added, so the 
network should not be attackable from the outside. AM I right with this?

Thans in Advance

Mit freundlichen Grüßen
Daniel Benden
