3) Network Configuration
This page is to define network type and set network addresses of NetServer.
(1) DHCP Client Protocol
DHCP (Dynamic Host Configuration Protocol) is to manage host address on a network. With this
protocol, every host on a LAN may share limited official IP address for Internet access. In other
words, every host on a LAN may lease official IP address from DHCP server temporarily. Exactly
speaking, DHCP server assigns a certain host with an official IP address that is not occupied by
other hosts on the LAN.
DHCP server will assign NetServer with an official IP address if the LAN is equipped with DHCP
server and ‘ DHCP Client Protocol’ is activated.
‘DHCP Client Protocol’ is to be used on a LAN where a DHCP server operates. Normally, medium
or large sized company runs a DCHP server on their LAN. For the small sized LAN, it would be
better to use NAT function of HUB.
(2) Select Network Interface
This is to select proper network interface with which NetServer is connected.
If NetServer is connected with Internet dedicated line, cable modem line or on LAN environment,
you should select network interface as ‘ Ethernet’ .
If NetServer is connected on xDSL line that needs PPPoE process to connect on Internet,
administrator should select ‘ xDSL (PPPoE)’ . However the xDSL line doesn’ t need PPPoE process,
administrator should select ‘ Ethernet’ though NetServer is connected on xDSL line.
If NetServer is connected on network with PSTN modem, administrator should select ‘ PSTN (Dial
Out)’ .
(3) Ethernet Interface
Administrator may configure IP address, subnet mask, broadcast address, gateway address, and
DNS addresses of NetServer. For broadcast address, administrator may set it automatically by
clicking ‘ Get From Netmask’ button after assigning IP address and subnet mask. When the
addresses are not assigned properly, any user cannot access NetServer from local or remote network.
Even on the local network, a user is not able to access if administrator does not assign a proper IP
address to NetServer. Please refer to appendix 3 ‘Utilizing IP Address on Local Network’ for more
detailed information.
This interface is mainly used for Internet dedicated line and LAN, and sometimes for xDSL line as
it is explained on ‘ DHCP Client Protocol’ setting.
