Hi, Hope this can help someone.

 

To connect local network storage, mine is DS1817+. Create port forward and connect thru internet.

Do reply here if you have better or easier configuration! =D

 

Configuration on Cisco Router:

ip nat inside source static udp 192.168.2.99 137 interface GigabitEthernet5 137

ip nat inside source static udp 192.168.2.99 138 interface GigabitEthernet5 138
ip nat inside source static tcp 192.168.2.99 139 interface GigabitEthernet5 139

ip nat inside source static tcp 192.168.2.99 445 interface GigabitEthernet5 445

A better configuration is to NOT do this. You're just asking to get hacked. Use a VPN to reach a SMB share on your local network, do NOT expose it to the internet.

@paul totally agree with you! but this way I can get faster transfer rate and lesser configuration. If you have confidential data, this is not recommended.
