Configuring ASA as dhcp server
In some cases, a network might not have a dedicated DHCP server. You can configure an ASA to act as a DHCP server, assigning IP addresses dynamically to requesting clients. The DHCP server can also generate dynamic DNS information, allowing DNS records to be updated dynamically as hosts acquire an IP address.
An ASA will return its own interlace address for the client to use as the default gateway. The interface subnet mask is returned for the client to use as well. You can define and enable DHCP servers on more than one interface, if clients are located there.
