If Linux assigned a 169.254 address to an Ethernet port then iptables should be set up for 169.254. But you can't use the link local "network" for unicast messages unless you have a link local address. I don't believe Linux will assign an 169.254 address by default if another IP address has been assigned manually or by DHCP.
