ASA 5505- ver 7.2(3).. unable to get DHCP ip from carrier. A laptop can get when directly connected to cable.
ASA configured with :
ip address dhcp setroute
dhcpd auto_config outside
The below I found in the Forum did not qwork:
7.2.3 or later you have a checkbox in ASDM Configuration / Interfaces / Outside / Edit / General. Check the value in "For the client identifier in DHCP option 61" - "Use Mac address".
