6.3 The Static DHCP Screen
This table allows you to assign IP addresses on the LAN to specific individual computers based on
their MAC Addresses.
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
6.3.1 Before You Begin
Find out the MAC addresses of your network devices if you intend to add them to the Static DHCP
screen.
DHCP Select Enable to have your LTE Device assign IP addresses, an IP default
gateway and DNS servers to LAN computers and other devices that are DHCP
clients.
If you select Disable, you need to manually configure the IP addresses of the
computers and other devices on your LAN.
When DHCP is used, the following fields need to be set.
IP Addressing Values
IP Pool Starting
Address This field specifies the first of the contiguous addresses in the IP address pool.
Pool Size This field specifies the size, or count of the IP address pool.
DNS Values
DNS Server 1-3 The LTE Device supports DNS proxy by default. The LTE Device sends out its
own LAN IP address to the DHCP clients as the first DNS server address. DHCP
clients use this first DNS server to send domain-name queries to the LTE
Device. The LTE Device sends a response directly if it has a record of the
domain-name to IP address mapping. If it does not, the LTE Device queries an
outside DNS server and relays the response to the DHCP client.
Select From ISP if your ISP dynamically assigns DNS server information (and
the LTE Device's WAN IP address).
Select DNS Proxy to have the DHCP clients use the LTE Device’s own LAN IP
address. The LTE Device works as a DNS relay.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS
server's IP address in the field to the right.
Select None to not configure extra DNS servers.
Apply Click Apply to save your changes.
Cancel Click Cancel to restore your previously saved settings.
