The LAN Configuration table displays the following settings:
Setting
Description
System Mode
The preconfigured mode for your device, such as
Routing or Bridging mode. This setting is not user -
configurable.
LAN IP
Address
The IP address your computers use to identify the
device’s LAN port.
Note that the public IP address assigned to you by your
ISP is not your LAN IP address. The public IP address
identifies the WAN (ADSL) port on your ADSL/Ethernet
router to the Internet.
LAN Network
Mask
The LAN Network mask identifies which parts of the
LAN IP Address refer to your network as a whole and
which parts refer specifically to nodes on the network.
Your device is preconfigured with a default network
mask of 255.255.255.0.
Use DHCP
When checked, this setting instructs the device to
accept LAN IP information assigned dynamically from
another DHCP server already configured on your
network. HSA300 cannot act as a DHCP server for its
own LAN port.
2. Enter a LAN IP address and network mask, or click the
DHCP Enable radio button.
! Entering a fixed address: If you are using routing services
on you LAN such as DHCP and NAT, you will want to
assign a fixed LAN IP address and mask. This ensures that
your LAN computers have a fixed address that they use to
communicate with the device.
The IP address you assign must be on the same subnet as
your LAN computers that connect to this port (that is, the
network ID portion of their IP addresses and their subnet
masks must be the same). See Appendix 0 for an
explanation of IP addresses and network masks.
You may need to update the DHCP configuration so that
the addresses that the DHCP server dynamically assigns
to your computers are on the same subnet as the new LAN
IP address. See Chapter 7 for instructions on changing the
pool of dynamically assigned addresses. In addition, if you
change the DHCP pool, you will also need to update the
NAT configuration so the new IP addresses are translated
properly. See Chapter 8 for instructions on NAT.
! Enabling DHCP: If another computer on your LAN
provides DHCP services for your network, you can click the
Use DHCP checkbox to enable the LAN port to accept a
dynamically assigned address from the server. Check with
your ISP to determine if this is advisable.
When you click the Enable radio button, the LAN Network
Mask field will be dimmed (made unavailable for entry).
The LAN IP Address field will remain editable, however.
The address that you specify here will be used as a
