Dear para Master Mikrotik !
Saya baca manual Mikrotik yang 2.9 di bagian Troubleshooting NAT ada statement sbb:
* The NAT rule does translate the addresses.
Add firewall rule that logs the packets and helps to determine where the problem is.
* The source or destination 0.0.0.0/0:0 does not match packet with any_address:any_port
Set the port to 0-65535, i.e., 0.0.0.0/0:0-65535.
* The NAT does not work when masquerading is in use.
Masquerading changes the source address of packets leaving the router ('outgoing' traffic). Therefore a firewall rule should be added to the forward chain, which excludes masquerading for the address

ort and protocol to be translated. (See the Application Example!)
ada yang bersedia untuk menjelaskan maksudnya (bukan terjemahannya yah :-) )
terima kasih atas perhatiannya
