Windows, there was a “security” gap during computer startup, before the IPSec policy was applied. Now, with Windows Server 2003, stateful filtering is used to prevent unsecured traffic from crossing the network. With this enabled, the computer only permits outbound traffic that it initiates during startup, inbound traffic that is a direct response to that outbound traffic, and DHCP traffic (which is necessary for the computer to obtain an IP lease and TCP/IP configuration information if it is a DHCP client). This increases security because other unsolicited inbound traffic is not allowed.
