•
Schedule: by default, the connection is always active. However, if you have
defined scheduler rules (refer to ''Configuring Scheduler Rules'' on page 122 ), you
can select one of these (time segments during which the connection is active).
•
Network: select whether the parameters you are configuring relate to a WAN,
LAN or DMZ connection.
•
Physical Address: physical address of the network card used for your network.
Some cards allow you to change this address.
•
MTU: Maximum Transmission Unit - specifies the largest packet size permitted for
Internet transmission. By default ('Automatic'), the device selects the best MTU for
your Internet connection. Select 'Automatic by DHCP' to have the DHCP
determine the MTU. If you select 'Manual', it is recommended to enter a value in
the 1200 to 1500 range.
•
Internet Protocol: select one of the following Internet protocol options from the
'Internet
♦ No IP Address - select this option if you require that your device have no IP
address. This can be useful if you are working in an environment where you
are not connected to other networks, such as the Internet.
♦ Obtain an IP Address Automatically - your connection is configured by
default to act as a DHCP client. You should keep this configuration in case
your service provider supports DHCP, or if you are connecting using a
dynamic IP address. The server that assigns the device with an IP address,
also assigns a subnet mask. You can override the dynamically assigned
subnet mask by selecting the 'Override Subnet Mask' check box and
specifying your own mask instead. You can click the
Release button to
release the current leased IP address. Once the address has been released,
the button text changes to
Renew . Use this button to renew the leased IP
address.
♦ Use the Following IP Address - your connection can be configured using a
permanent (static) IP address. Your service provider should provide you with
such an IP address and subnet mask.
•
DNS Server: Domain Name System (DNS) is the method by which Web site
domain names are translated into IP addresses:
♦ Obtain DNS Server Address Automatically - configure the connection to
automatically obtain a DNS server address, or specify such an address
manually, according to the information provided by your ISP.
♦ Use the Following DNS Server Addresses - manually configure DNS server
addresses. You can specify up to two different DNS server addresses, one
primary, another secondary.
•
IP Address Distribution: allows you to configure the device's Dynamic Host
Configuration Protocol (DHCP) server parameters. The DHCP automatically
assigns IP addresses to network PCs. If you enable this feature, ensure that you
also configure your network PCs as DHCP clients:
♦ DHCP Server:
9 Start IP Address: first IP address that may be assigned to a LAN host.
Since the device's default IP address is 192.168.1.1, this address must
be 192.168.1.2 or greater.
9 End IP Address: last IP address in the range that can be used to
automatically assign IP addresses to LAN hosts.
9 Subnet Mask: mask used to determine to what subnet an IP address
belongs.
