VSFTPD Passive Mode doesn't work Behind NAT

Question

Hey guys so I am trying to allow my friends to connect to my ftp server (I am hosting it on Ubuntu Server 15.04), so I set the pasv_address in the configuration and the port range in the configuration and router. But it still doesn't work. Here is what filezilla says:

Response: 227 Entering Passive Mode (0,0,0,0,203,228). Command: LIST Error: The data connection could not be established: ECONNREFUSED - Connection refused by server Error: Connection timed out Error: Failed to retrieve directory listing

And here is my configuration: http://pastebin.com/j1ZyK7K8

Solution 1

Late answer, but here goes:

I have all the options turned on like you. It is required, but still won't work.

pasv_enable=YES
pasv_min_port=xxx
pasv_max_port=yyy
pasv_address=

After these 2 lines change, it is working

listen_ipv6=NO
listen=YES

Solution 2

sudo nano /etc/vsftpd.conf

pasv_enable=Yes

pasv_max_port=10100

pasv_min_port=10090

---

iptables -I INPUT -p tcp --destination-port 10090:10100 -j ACCEPT

---

sudo ufw allow 10090:10100/tcp

---

Try allowing Anon login to make sure its not a user/pwd problem. Not sure what pasv_address is. but I have a domain name, so maybe its needed for IP? BTW Check out duckdns for free DNS!

Are you sure your ISP allows you to run an FTP server on your internal network? (some ISPs "up-sell" you a "business connection" that do allow you to do things like this)

I used to have it working, a few months ago, but I accidentally crashed the server and I couldn't access it to see what I did.

@derek-lesho: if the above doesn't work, drop me a note @ Fabby below.

I tried this but I am still having the same error. When entering passive mode it says:Command: PASV Response: 227 Entering Passive Mode (0,0,0,0,39,106). Why are there 0s instead of the ip?

[Derek Lesho]

Do you want me to send the ip and password of my server so you ssh into it and try to find the problem?
