In-Depth Information
Remember that renewal attempts begin when approximately half of the
lease period is over (give or take a random interval), so don't set them too
short.
Configuring Basic DHCP Options
The Configure DHCP Options page (see Figure 2.22) allows you to choose whether you
want to set up basic DHCP options such as default gateway and DNS settings. The options
are described in the following sections. If you choose not to configure options, you can
always do so later. However, you should not activate the scope until you've configured the
options you want assigned.

Configuring a Router
The first option configuration page is the Router (Default Gateway) page (see Figure 2.23),
in which you enter the IP addresses of one or more routers (more commonly referred to as
default gateways
) that you want to use for outbound traffic. After entering the IP addresses
of the routers, use the Up and Down buttons to order the addresses. Clients will use the
routers in the order specified when attempting to send outgoing packets.
Providing DNS Settings
On the Domain Name And DNS Servers page (see Figure 2.24), you specify the set of
DNS servers and the parent domain you want passed down to DHCP clients. Normally,
you'll want to specify at least one DNS server by filling in its DNS name or IP address. You
can also specify the domain suffix that you want clients to use as the base domain for all
connections that aren't fully qualified. For example, if your clients are used to navigating
based on server name alone rather than the fully qualified domain name (FQDN) of
server.willpanek.com
, then you'll want to place your domain here.
