the local device will send a packet to a gateway, and the gateway will send the packet to another
subnet. If the setting of a subnet is incorrect, a destination device can not communicate with
DVP-FEN01 normally. Users can judge whether the IP address of a destination device and the IP
address of a local device are in the same subnet by performing a bitwise AND operation between
the IP address of the local device and the subnet mask, and a bitwise AND operation between the
IP address of the destination device and the subnet mask. If the two values gotten are the same,
the IP address of the destination device and the IP address of the local device are in the same
subnet. The default subnet mask of DVP-FEN01 is 255.255.255.0.
(4) Default gateway
A gateway is a network point that acts as an entrance to another network. For example, in order
to connect a local area network and a wide area network, a gateway is needed. The IP address
that a gateway uses and the IP address of DVP-FEN01 must be in the same subnet. The default
gateway of DVP-FEN01 is 192.168.1.1.
3.
Setting keepalive time
Keepalive time is a TCP keepalive period. A second is a unit. The default keepalive time set for
DVP-FEN01 is 30 seconds. After DVP-FEN01 and other devices are connected to a network,
DVP-FEN01 will be automatically disconnected from the network to avoid too many connections if no
network packet is sent during the period.
 Setting a network in a computer
All network devices which will be connected to networks need internet protocol addresses (IP addresses).
The IP addresses are like numbers, and are used to identify the identities of these network devices on the
networks.
