Chapter 9 DHCP Server
DESCRIPTION
This field is configurable only when you select DHCP Relay.
Enter the IP address of the actual remote DHCP server in this field.
This is the period of time DHCP-assigned addresses is used. DHCP automatically
assigns IP addresses to clients when they log in. DHCP centralizes IP address
management on central computers that run the DHCP server program. DHCP leases
addresses, for a period of time, which means that past addresses are "recycled" and
made available for future reassignment to other systems.
Select Enable to activate DHCP for the VLAN group.
Enter the LAN IP address you want to assign to your LTE3301 in this VLAN group.
Specify the IP addresses up to two DNS servers for the DHCP clients to use.
Select Obtained From ISP if your ISP dynamically assigns DNS server information
(and the LTE3301's WAN IP address). The field to the right displays the (read-only)
DNS server IP address that the ISP assigns.
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 DNS Relay to have the LTE3301 act as a DNS proxy. The LTE3301's LAN IP
address displays in the field to the right (read-only). The LTE3301 tells the DHCP
clients on the LAN that the LTE3301 itself is the DNS server. When a computer on the
LAN sends a DNS query to the LTE3301, the LTE3301 forwards the query to the
LTE3301's system DNS server (configured in the WAN screen) and relays the
response back to the computer.
Click Apply to save your changes back to the LTE3301.
Click Cancel to begin configuring this screen afresh.
