Step 3: Configure DHCP options for clients. Step 2: Create an address pool for clients on an interface: Wins Configure the IP addresses of the NETBIOS servers after thisĪvailable interfaces on which to enable the DHCP server: Ping_timeout Configure ping timeout value after this keyword Option Configure options to pass to DHCP clients after this keyword Lease Configure the DHCPD lease length after this keyword Step 1: Enable the DHCP server on an ASA interface that faces the clients:Īddress Configure the IP pool address range after this keywordĪuto_config Enable auto configuration from clientĭns Configure the IP addresses of the DNS servers after thisĭomain Configure DNS domain name after this keyword You can configure the DHCP server feature on the ASA via CLI using the following steps: Meaning, no reserved IP address for a specific client or network device (ip dhcp excluded-address in router IOS). Note that an ASA can only manage dynamic IP address assignments from its DHCP pool. You can define and enable DHCP servers on more than one interface, if clients are located there. The interface subnet mask is returned for the client to use as well. The DHCP server can also generate dynamic DNS information, allowing DNS records to be updated dynamically as hosts require an IP address.Īn ASA will return its own interface address for the client to use as the default gateway.
You can configure an ASA to act as a DHCP server and assign dynamic IP addresses to requesting clients.
