Help: Can't connect to my FileZilla FTP-server from another network

[Djeunut]

So I've been trying to get access to my FileZilla server from another network and I was able to connect the normal way but it wouldn't load my files.

I found an old post on this issue on stack overflow where they solved it by using SFTP.
I started trying this but now I'm completely unable to connect to my FTP server.

What could I possibly try now?
 

Thanks in advance

Is this over the Internet, or a different subnet that should have a route back to the network your FTP server lives on?

 

If it's over the Internet, your traffic is probably getting stopped by your firewall. Opening FTP to the public Internet is a very bad idea for a variety of reasons, you're better off running a VPN like Wireguard instead.

Yes it is going over the internet but since it isn't safe I'm trying to get it to work with SSH (SFTP).

I did add a rule in my windows firewall to let FileZilla and its port through which did work when I was using regular FTP but after trying to use SFTP I couldn't connect anymore.

FTP uses "Passive mode" so in addition to port 21 you also have to open another range of ports that will be used for the actual transfers, those need to match the settings in your server.

I did think I had to do something like this but every tutorial or discussion online didn't mention this once.

I'll try opening some of these ports and try connecting again.

Small update:

For some reason the connection I tried earlier showed up much later in my server console.

I opened the ports but I'm still not getting anywhere, I'm still getting the same error.

I think I just misconfigured something but I can't figure out what.

Is your PC connected directly to the Internet?  If not, are you port forwarding to that PC on the router?

 

Don't even bother with FTP though, SSH is much easier and safer to deal with as you only need a single port and traffic is encrypted.

I did port forward my pc but I just can't get SSH to work but I don't know what I'm doing wrong.

90% of the issues I see people having with Port forwarding is caused by multiple layers of NAT or something miss configured. 

 

Multi layers of NAT is caused by connecting multiple routers in a chain OR can be caused by the fact the ISP uses NAT on its network because they dont have enough IP addresses for everyone. You can check for the ISP's NAT by looking at your WAN IP and seeing if it falls with in the range used by Carrier Grade NAT,.

Don’t use FTP… but it certainly sounds like a double NAT issue. Do you have multiple routers? Who is your ISP (they me be using C-NAT).
