The
Min Data Rate
text field requires the amount of upstream bandwidth that ought to remain for data applications even if voice applications use the
entire available upstream bandwidth. The value selected here needs to be smaller than the upstream bandwidth and is measured in kbit/s.
The
WAN IP Configuration
page is only displayed if
Ethernet
or
PPTP
has been selected to be the uplink protocol. It offers the
following components:
The
Assign automatically via DHCP
radio-button selection switches
to automatic retrieval of the WAN IP address from a DHCP server at
the ISP/uplink.
Please Note:
DHCP referred to here is the one that runs on the
provider’s side and not the Quadro’s personal DHCP server.
The
Assign Manually
radio-button switches to the manual
adjustment of IP settings. This selection requests the following
parameters:
IP Address
requires the IP address for the Quadro WAN interface.
Subnet Mask
requires the subnet mask for the Quadro device WAN
interface.
Default Gateway
requires the IP address of the router where all
packets are to be sent to, for example, to the router of the provider.

The
WAN Interface Configuration
page may be used to modify the
MAC address of the Quadro. This might be necessary if the ISP
(Internet Service Provider) requires a specified MAC address, for
example, for authentication. This page offers the following
components:
MAC Address Assignment
manipulation radio-buttons:
•
This Device
turns to the default MAC address of the Quadro.
•
User Defined
requires user defined MAC Address.
The
MTU
drop down list allows you to select the maximum packet
size on the Ethernet (in bytes). MTU is used to fragment the packets
before transmitting them to the network. The MTU preferred value is
dependent on the Ethernet connection. The default MTU size is 1500
Bytes for Ethernet and 1400 Bytes for PPPoE.
Please consult with your ISP administrator to get the corresponding
settings.
