DHCP Server
, you can select to use either the interface’s IP
address or another IP address as the default router. This default router will become the
DHCP clients’ default gateway.
To use another IP address as the default router, select
Custom Defined
and enter the
IP address.
Lease time
Specify how long each computer can use the information (especially the IP address)
before it has to request the information again. Choices are:
infinite
- select this if IP addresses never expire
days
,
hours
, and
minutes
- select this to enter how long IP addresses are valid.
