Page 53: Glossary
When a network device wants to send an IP packet to a destination that is not on the same network, the device sends the packet to a default gateway, which will send it out towards the destination. In the case of the BR4100DC, the router’s IP address acts as a default gateway. - Page 54 Ethernet: A popular network standard of communication using either twisted pair or coaxial cables. The most widely used LAN access method, Ethernet networks are connected by special cables and hubs, and can transfer data at speeds up to 10 or 100 million bits per second (Mbits/sec).
- Page 55 Port: A number used to identify a specific process or application (such as HTTP or SMTP) to which an Internet or other network message is to be forwarded. If you are operating behind a firewall, you may need to open specific ports to allow users to access these applications.
