Cisco ASA: DHCP relay

Technology: Network Security
Area: Firewalls
Vendor: Cisco
Software: 8.X, 9.X

Cisco ASA provides a DHCP relay service to DHCP clients attached to ASA interfaces. DHCP relay passes DHCP requests received on one interface to an external DHCP server located behind a different interface.

 

To configure DHCP relay on ASA with DHCP server of 10.120.65.11 use following commands:

dhcprelay server 10.120.65.11 core
dhcprelay enable inside

 

Core interface is where server resides (direction on the way to server) and inside is the client resides (requesting for IP addresses).
