When a firewall is set to 'block all traffic' what happens to inbound packets? Are they closed or stealth? If someone were to try to connect to one of my ports would my firewall respond saying its closed? Yet another option I would like to see on future firewalls! Block All Traffic - No outbound packets connect to remote systems - - All ports closed - Stealth All Inbound/Block Outbound - No outbound packets connect to remote systems - - ALL packets reguardless of protocol from ANY remote IP/port to ANY of my ports will be dropped with NO response from my system - Usefull for those who do not have a hardware router or a standby button on their always on connection like DSL. If a person forgot to shut down the computer it would go into a no response/total traffic block mode after a while.
