Help with Hairpin on RB750 not working

With dynamic ip on wan I can not set hairpin for my internal network following this :
http://wiki.mikrotik.com/wiki/Hairpin_NAT

These are my nat rules :

 0   ;;; APACHE
     chain=dstnat action=dst-nat to-addresses=192.168.9.10 to-ports=80 
     protocol=tcp in-interface=ether1-gateway dst-port=80 

 1   ;;; DEFAULT
     chain=srcnat action=masquerade out-interface=ether1-gateway 

 2   ;;; APACHE FROM LAN
     chain=srcnat action=masquerade protocol=tcp src-address=192.168.9.0/24 
     dst-address=192.168.9.10 out-interface=ether3-master-omicron dst-port=80

Port forwarding from outside is working OK.

Errors ? Missing something ? Thanks in advance
