5.7.2. DHCP Server
This section can be used to individually configure the Dynamic Host Configuration
Protocol (DHCP) service for each LAN interface which will serve dynamic IP addresses
to hosts in the local network. You may also have a look to the status page where you
can find an overview about negotiated client addresses.
Please note that WLAN interfaces (for each SSID) will pop up here as well in case you
have configured an access point respectively.
The following settings for each interface can be applied then:
Parameter DHCP Server Settings
Operation mode Specifies whether the DHCP server is enabled or not
First lease address The first address out of the range of IP addresses given to
hosts
Last lease address The last address out of this range
Lease duration Number of seconds how long a given lease shall be valid
until it has to be requested again
Persistent leases By turning on this option the router will remember issued
leases even after a reboot. This can be used to ensure that
the same IP address will be assigned to a particular host.
DHCP options By default the DHCP will hand out the interface address as
default gateway and the current DNS server addresses if not
configured elsewise. You can specify fixed addresses here.
Only allow static hosts Any requests coming from none-static hosts will be ignored.
It is also possible to configure specific lease addresses for particular clients.
Parameter DHCP Static Hosts Settings
IP address The IP address of the lease
Identified by Specifies by which criteria the client shall be identified
MAC address The MAC address of the client
hostname The client identifier (DHCP option 61)
port The Ethernet port on which the DHCP request is received
