•
Disabled
The device does not assign local IP addresses.
•
Enabled
The device assigns IP addresses to client
devices on the local network.
-
Range Start and End
Determines the range of IP
addresses assigned by the DHCP server.
-
Netmask
Defines the device IP classification for the
chosen IP address range. 255.255.255.0 is a typical
netmask value for Class C networks, which support
an IP address range of 192.0.0.x to 223.255.255.x. A
Class C network netmask uses 24 bits to identify the
network (alternative notation “/24”) and 8 bits to
identity the host.
-
Lease Time
The IP addresses assigned by the DHCP
server are valid only for the duration specified by
the lease time. Increasing the time ensures client
operation without interruption, but could introduce
potential conflicts. Decreasing the lease time avoids
potential address conflicts, but might cause more
slight interruptions to the client while it acquires a
new IP address from the DHCP server. The time is
expressed in seconds.
-
DNS Proxy
The Domain Name System (DNS) proxy
server forwards the DNS requests from the hosts on
the local network to the DNS server.
•
Relay
Relays DHCP messages between DHCP clients
and DHCP servers on different IP networks.
-
DHCP Server IP
Specify the IP address of the DHCP
server that should get the DHCP messages.
-

Specify the identifier of the DHCP relay
agent.
