Trying to allow FTP connection to NAS outside of network using OMV

I am trying to set up the ability to FTP into my NAS from a network outside of my home network. I am a bit confused as to how to do this. People have said I should be able to do this without extra crap like docker and tailscale etc. Any help is appreciated. TIA!

Yes, but you have to forward the ports in your router. But I would rather recommend a VPN. Because if you forward the ports from the router, your server is open to the Internet. And if you don't have any experience with securing the server, it's not safe!

I was trying to look at some tutorials for setting up docker and tailscale but they seemed daunting and every tutorial was different so I have no idea how to set it up and which direction to go in

I also don't want to have to use yet another piece of software just to access it from another location

I use filezilla, and would like to remain using something as simple as that. I also have a shared folder that a friend would have access to so they can offload some of their data onto it, they'd need to be able to access their folder..

Well it's your server, if you don't have a problem with everyone getting access if it's not properly secured... And I'm not talking about tailscale. Wireguard, for example, would be a simple VPN. How exactly does your friend have access to this folder?

they don't yet, but I would like to have the ability to share it if I need. But if that makes it overly complicated, no biggie. At very minimum I'd like to be able to access my NAS from outside my network.

mostly so I can be somewhere and pull data to my phone or laptop to work on it, and put it back onto the NAS when completed.

Complicated is relative. You just have to be careful because otherwise the server is unprotected on the Internet and any hacker will use it. What kind of router do you have?

whatever my ISP provided me with. It is a Calix GigaSpire BLAST u6.2 https://www.brightspeed.com/help/internet/fiber/equipment/calix-u6.html

It doesn't seem that you can use Wireguard directly on it, too bad that would have been easiest. So I still recommend a VPN, it's safer if you have little experience. However, I can't help you set it up. If you still prefer to forward ports, make sure you secure your server. Strong passwords, fail2ban, that helps against login attempts, always keep the server up to date, install what is really necessary. And what you need to find out first is whether you have a public IP. more secure

vpn like tailscale?

No idea what everyone has with tailscale all of a sudden... I would just use Wireguard.

I agree with Thunder, the work to get FTP accessible is as much to get a VPN solution up and running and the advantages with a VPN is far more than with FTP. And some internet providers block FTP servers on their internet as it is inherently insecure.

yeah I am going to look into tailscale. Looks like that is what I need to get setup to get this running. I'll worry about that later. For now, just local access works I suppose.
