Hi everyone,
I'm fairly new at networking stuff and I have a problem setting up an FTP server at home.
So this is the situation.
I want to use my QNAP TS-219P as a FTP server. I have a WRT160 v1 router linked to my modem and the entire network (including the QNAP).
As I understand to establish an FTP server, you need to forward a port on the router to the static IP of your FTP server. By default this is 21. Now here lies the problem.
My ISP blocks all incoming port below 1024, so port 21 is not available for mee to use to access the FTP outside the network.
I did get the FTP server running (only inside the network) by opening the default FTP port on the WRT160N (on the admin page: applications&games > Forward a single port > enabling the FIXED application "FTP" and putting in the QNAP IP address).
So I tried to set-up my FTP server by opening a port higher than 1024 on my router (e.g. external port and internal port = 8000) and changing the access port to 8000 on my QNAP. When I do this, I can't connect to the FTP inside as well as outside the network.
Because I didn't know what was causing the problem I reset the FTP port on my QNAP to default 21 and changed the internal port on my router to 21 (keeping external port to 8000). Still nothing. If the QNAP was causing the problem, it would be fixed doing this, I think.
As far as I can tell from this Open Port Tool DynDNS.com - Support -- Tools -- Open Port Tool port 8000 on my router is open and should be working. So this tells me, my ISP is not the problem either.
From what I tried, I think my WRT160N is causing the problem by not allowing an FTP to go through any other port than 21. Like I said the FTP works fine inside the network but only if I use the FIXED port forward (the 5 rows in the port forwarding section have a top-down menu where you have to select a fixed application, automatically assinging the port for this application).
But if I manually make an application (using the 6th row or higher and type the port 21 (internal & external port) going to the LAN IP of my QNAP, I can't even access the FTP from inside the network. For clarification, i put in a link where you see a screen shot of the port forwarding page of my router).

Because of this, I think some weird firmware issue is causing this problem by not allowing me to manually assign a port for the FTP.
Does anybody have an idea about this, or some experience maybe? Is it in fact the firmware of the router that is causing the problem? And if so, could I fix this by installing other firmware, like DD-WRT? I hear a lot of good things about this but I want to make sure this will actually fix my problem before I install it.
Thanks in advance!
