NOTE: leave blank to use the system default DNS servers - this interface's IP if DNS forwarder is enabled, otherwise the servers configured on the General page.

Gateway

The default is to use the IP on this interface of the firewall as the gateway. Specify an alternate gateway here if this is not the correct gateway for your network.

Domain name

The default is to use the domain name of this system as the default domain name provided by DHCP. You may specify an alternate domain name here.

Domain search list

The DHCP server can optionally provide a domain search list.

Default lease time

seconds
This is used for clients that do not ask for a specific expiration time.
The default is 7200 seconds.

Maximum lease time

seconds
This is the maximum lease time for clients that ask for a specific expiration time.
The default is 86400 seconds.

Failover peer IP:

Leave blank to disable. Enter the interface IP address of the other machine. Machines must be using CARP.
