DHCP server: Settings for automatic network configuration
Setting Meaning
DHCP server IP addresses from:: Define the IP address
as of which the TNC is to derive the
pool of dynamic IP addresses. The TNC
transfers the values that appear dimmed
from the static IP address of the defined
Ethernet interface; these values cannot be
edited.
IP addresses to: Define the IP address up
to which the TNC is to derive the pool of
dynamic IP addresses
Lease Time (hours): Time within which
the dynamic IP address is to remain
reserved for a client. If a client logs on
within this time, the TNC reassigns the
same dynamic IP address.
Domain name: Here you can define a
name for the machine network if required.
This is necessary if the same names are
assigned in the machine network and in
the external network, for example.
Forward DNS externally: If IP
Forwarding is active (Interfaces tab) and
the option is active, you can specify that
the name resolution for devices in the
machine network can also be used by the
external network.
Forward DNS from outside: If IP
Forwarding is active (Interfaces tab) and
the option is active, you can specify that
the TNC is to forward DNS inquiries from
devices within the machine network to
the name server of the external network if
the DNS server of the MC cannot answer
the inquiry.
Status button: Call an overview of the
devices that are provided with a dynamic
IP address in the machine network. You
can also select settings for these devices.
Additional options button: Additional
settings for the DNS/DHCP server.
Set standard values button: Set factory
settings.
