Help needed with accessing NAS Drive using DYNDNS

[Softoit]

I have a Nexstar FX NAS Adapter and I have a Hard drive connected to it.
From my LAN I can access FTP and do everything on in.
Now for the problem
I have registered a .com domain and have registered at DYNDNS what do I need to setup to make my nas drive accessible from outside my LAN
I have a Duoplus 300 adsl router. When I run the dysdns updated and try to access the new IP address I only get to the Duoplus 300 adsl router how can I make it see the NAS Drive
In Short I want to access the NAS device … how the hell do I do that

Setup port forward on your router to point to your internal device

The NAS device needs to have a static IP address (internal router assigned IP, you can set it up to have DHCP assign it the same one each time)

Once that's done, you need to port forward port 21 to that IP address. Then when any traffic for port 21 comes in from the dyndns address/ip address, the router knows where to send the traffic.

Remember, when you're on your network and you access a website like google.com, google sends it back to the originating IP address that made the request, the router remembers who on it's own network made the request and then forwards the traffic to the PC waiting for the data. When a router receives data from the outside and it doesn't have any record of anyone within it's own internal network requesting this data, it doesn't know what to do with it. Some routers ignore it and times out, others will show you the router home page.

If you remember that, you'll soon be a network routing guru
