Filtering on the destination IP address allows the firewall or router to distinguish between requests aimed at public servers in the DMZ (which have externally reachable IP addresses) and those intended for the internal LAN (which typically uses private IP addresses). This ensures that external hosts can access public services without gaining access to the internal network.
