Enable Client – Some other device on the LAN side of the network is acting as a DHCP server. The router will be
assigned a dynamic IP address by the DHCP server.
DNS Address Source – In most cases this parameter should be set to Acquire From Wireless Network. In this case,
when you click on the Update button, the router will verify that it has been connected to the wireless network and that the
wireless network has provided DNS addresses. If DNS addresses have been provided, they will be displayed in the
Primary and Secondary Address boxes. If addresses have not been provided, you will receive an error indication. At that
point, you should allow the router to establish a connection with the wireless network so that it can acquire the DNS
addresses. You should then go back into the Ethernet Configuration screen and click on submit again. At this point, the
DNS addresses should appear.
If you application requires a specific DNS setting check the User Defined box and manually fill in the DNS IP Address
fields below.
DNS IP Address (Primary and Secondary) – The address of the Domain Name Server that your network uses. This
should not be confused with the Name Server entries on the Wireless Interface screen. The DNS referenced by these
addresses will resolve outbound queries.
IP Address – The IP address assigned to the LAN segment of this router.
NetMask – This parameter is also known as Subnet Mask. Network Mask determines which portion of an IP address is
the network portion and which portion belongs to the host. As an example a setting of 255.255.255.0 would indicate that
the first three groups of this address (255.255.255) identify the network and that the last group (000 – 254) identify a
particular host.
Default Gateway – The Default Gateway is the address of a device that the router will use to reach remote networks or
servers. In many cases this will be a firewall address. In a normal situation where the Z4300 is acting as a fringe router
and is expected to pass incoming Ethernet traffic through to the network, this field should be left blank. If the router is
acting as a RAS where traffic is coming in from the network so that it can be routed through to some sort of host/server,
this field must set to an address on the Z4300’s LAN segment.
Broadcast Address
If applications on the router need to do a broadcast operation, this is the address that will be used on the Ethernet
segment to fulfill the broadcast request.
