Default gateway assignment
The router always assigns the requesting computer its own IP address as a gateway
address.
If necessary, this assignment can be overwritten with the settings on the workstation
computer.
Period of validity for an assignment
The addresses assigned to the computer are valid only for a limited period of time. Once
this period of validity has expired, the computer can no longer use these addresses. In
order for the computer to keep from constantly losing its addresses (above all its
IP address), it applies for an extension ahead of time that it is generally sure to be
granted. The computer loses its address only if it is switched off when the period of
validity expires.
For each request, a host can ask for a specific period of validity. However, a DHCP server
can also assign the host a period of validity that differs from what it requested. The
DHCP module provides two settings for influencing the period of validity:
K
Maximum lease time in minutes
Here you can enter the maximum period of validity that the DHCP server assigns a
host.
If a host requests a validity in excess of 6000 minutes, this will nevertheless be the
maximum available validity!
The default setting is 6000 minutes (approx. 4 days).
K
Default lease time in minutes
Here you can enter the period of validity that is assigned if the host makes no
request. The default setting is 500 minutes (approx. 8 hours).
Priority for the DHCP server—request assignment
In the default configuration, almost all the settings in the Windows network environment
are selected in such a way that the necessary parameters are requested via DHCP. Check
the settings by clicking

Network . Select the
'TCP/IP' entry for your network adapter and open Properties .
Check the various tabs for special entries, such as for the IP address or the standard
gateway. If you would like all of the values to be assigned by the DHCP server, simply
delete the corresponding entries.
Priority for computer—overwriting an assignment
If a computer uses parameters other than those assigned to it (e.g. a different default
gateway), these parameters must be set directly on the workstation computer. The
computer then ignores the corresponding parameters assigned to it by the DHCP server.
