Field Reference
DHCP Relay IPv6 Page
Use the DHCP Relay IPv6 page to configure DHCPv6 relay services for security devices. Dynamic Host
Configuration Protocol v6 (DHCPv6) relay passes DHCPv6 requests received on one interface to an
external DHCPv6 server located behind a different interface. To configure DHCPv6 relay, you need to
specify at least one DHCPv6 relay server and then enable a DHCPv6 relay agent on the interface
receiving DHCPv6 requests.
Note You cannot enable a DHCPv6 relay agent on an interface where a DHCPv6 relay server is configured.
The DHCPv6 relay agent works only with external DHCPv6 servers; it will not forward DHCPv6
requests to a security appliance interface configured as a DHCPv6 server.
When clustering is enabled on the device, DHCPv6 is not supported.
Navigation Path
•(Device view) Select Platform > Device Admin > Server Access > DHCP Relay IPv6 from the
Device Policy selector.
•(Policy view) Select PIX/ASA/FWSM Platform > Device Admin > Server Access > DHCP Relay
IPv6 from the Policy Type selector. Select an existing policy from the Shared Policy selector, or
create a new one.
Note Two new interface settings have been introduced for DHCPv6: "managed-config-flag" and
"other-config-flag." For more information, refer to Configuring IPv6 Interfaces
(ASA/FWSM), page 45-29.
