is shown in the following figure. This reduces the total IP
number of a network able to support, by the amount of 2
power of the bit number of subnet number (2^(bit number of
subnet number)).
Subnet mask is used to set the subnet mask value, which
should be the same value as that of the other devices resided
in the same network it attaches.
For more information, please also see the Section 2-1-5 “IP
Address Assignment” in this manual.
Default: 255.255.255.0
Default gateway: Set an IP address for a gateway to handle those packets that
do not meet the routing rules predefined in the device. If a
packet does not meet the criteria for other pre-defined path,
it must be forwarded to a default router on a default path.
This means any packet with undefined IP address in the
routing table will be sent to this device unconditionally.
Default: 192.168.1.254
DNS Server You can set the DNS server by manual or auto when the
DHCP is enabled. Only manual setting is supported when
