Note: Leases are remembered over a re-configure or reboot of the firewall.
The DFL-200 also includes a DHCP Relayer. A DHCP relayer is a form of gateway
between a DHCP Server and its users. The relayer intercepts DHCP queries from the users
and forwards them to a DHCP server while setting up dynamic routes based on leases. This
enables the firewall to keep an accurate routing table based on active users and protects the
DHCP server to some degree among other things.
