If your ISP provide only dynamic IP address (external), follow below steps (you have done some parts):
- Register a Dynamic DNS Service (Hostname) at any Dynamic DNS Service provider.
Most of them are free of charge for basic use. (Dyndns.com etc, you may search from Internet)
- If your router support Dynamic DNS updating, fill in necessary information such as Hostname, Domain Name,
User Name, Password in your router.
Or, you may download an Updater (software) and install in your PC.
In this case, you have to take note that your external IP address (=router IP address) may change after certain
period. (Different according to ISP. My one is about every 72 hours) And, definitely will change whenever you reboot
your router. Make sure your external IP address registered with your Hostname is same with actual external IP
address before you try to access files by using FTP connection. You may update your external IP address with your
Hostname by running the Updater.
- Forward TCP port 21 to your MBL IP address (internal) at your router. MBL IP address must be set static at UI, or
you may set your DHCP server (at router) to always assign same IP address to MBL base on the MAC, if your router
support this function.
- Even though you can access FTP server through Web browser, it is easier to use a FTP Client. Follow the
instruction of the FTP Client manual for how to connect to your server. Normally, informations require to connect are
the Hostname that you registered with Dynamic DNS Provider, User Name and the Password that you created at
Be careful that data transfer through FTP is not encrypted and therefore is not secured.
