12.5 External Firewalls
• Gateway (0.0.0.0) means the destination host is directly attached to the node.
• Interface (pdcc0) indicates that a SDH SDCC interface is used to reach the destination host.
Entry 5 shows a DCC-connected node that is accessible through a node that is not directly connected:
• Destination (172.20.214.94) is the destination host IP address.
• Mask (255.255.255.255) is a 32-bit mask, meaning only the 172.20.214.94 address is a destination.
• Gateway (172.20.214.93) indicates that the destination host is accessed through a node with IP
address 172.20.214.93.
• Interface (pdcc0) indicates that a SDH SDCC interface is used to reach the gateway.
