VMG8823-B50B - Open port (5000) for access by ftp from outside my house

Hi,
from a LAN of my VMG8823-B50B (firmware V5.13(ABOV.0)b1_20180824) to my WAN of my netgear D6400 I connect my pc and an hard disk (using usb of my netgear) because I want to use my netgear for all services and my zyxel only for my fiber access. 
Now I opened too port 5000 on my netgear for access to  hd by ftp and I wanted to open port 5000 into my zyxel to access it from outside my house. I can't open it also if I tried to set port forwarding or port triggering. 
I can do this only if I add my netgear with address 192.168.1.254 into DMZ. 

I don't want this but I want to open only one port to access to hd. 
The port is open in my netgear when I set dynamic dns.

Can you help me?Did I make a mistake?
Regards

    If I understand it correctly, it looks like this:
    Internet --- zyxel --- (netgear + usb hdd)

    Also: zyxel modem is on 192.268.1.1 and netgear on 192.168.1.254. Is this correct?

    How do you connect to the usb hd from the LAN side?

    yes, it looks like this:Internet --- zyxel --- (netgear + usb hdd).

    hdd is connected by one usb port of netgear, so, when I'm in LAN I find \\readyshare and I can see all folder of hdd.

    But, from outside my home, if I want to see same folders I resolved only adding my netgear with address 192.168.1.254 into DMZ.

    I'm unable, or I did understand, how I have to open port 5000 on my zyxel.
    I hope this help. Thanks

    Can you try this, please?

    1. from LAN, can you access the hd via ftp (using port 5000)?
    2. instead of using DMZ, try setting 192.168.1.254 in NAT rule; can you access via ftp from outside (still using port 5000)?

    Hi Genius19,

    Could you provide the full topology from your side?
    What’s the result for VMG8823-B50B LAN side client access to Netgear port 500? Will it be successful?

    1) Yes, I can access the hdd via ftp (using port 5000) from LAN.
    2)I don't know how I have to set 192.168.1.254 in NAT rule. Can you tell me more?

    Anyway I received this reply about my firmware.

    Hi Genius19, 

    if you go to Network setting / NAT / Port forwarding / Add new rule or Edit existing rule, you should find the "Server IP Address" field.
    Set it up with the Netgear ip address.

    For example, my setup is like this:
    Internet --- Zyxel --- (raspberry pi + usb hdd)

    The raspberry pi runs a ssh/sftp server; remote access works fine.

    Zyxel model VMG8823-B50B, provided by Wind/Infostrada.

    @NeAl Have I to set in this way or I have to insert my router zyxel in "IP server address"?Have I to insert "IP sorgente"? Regards

    You are aware that opening a single port is not enough to support FTP? Unless you are using active FTP, but in that case you'll have to forward some ports on the client side.
    FTP uses a command port on 21 (which could be changed to 5000, of course), but also a pool of data port, which on most servers by default use the whole range 1024...65534. Sometimes it's possible to specify a smaller range, in which case you can forward a smaller range.

    Hi Genius19,
    I have both "Configurare IP Originario" unchecked and "IP sorgente" blank.
    Also, keep in mind that I'm using sftp.

    If you have to use ftp, as Mijzelf pointed out, check whether you need to forward a whole range of ports.

    mmh...how can I use sftp?Where I can set it?

    Check if it is available on the Netgear, instead of ftp.
