I have an ASA acting as a DHPCD server. When I connect a laptop directly to the inside interface the dhcpd bindings show as issuing the correct 10.x.x.x address to the user but their ipconfig shows a 169.254.0.x address, and the arp table on the ASA shows an additional 01 on the beginning of their mac address.
Its stumped me.
Here is a sanitised config. I cannot see anything different or odd.
I cannot ping the dhcp address issued inside, nor the 169.254.0.x address the user sees on ipconfig.
