I have set up a Vsftp server using the following instructions provided Here and even went as far as following the commentary at the bottom. But I am unable to connect remotely. When I attempt to use FileZilla or my Ubuntu terminal, I always get:

ryan@ryan-Galago-UltraPro:~$ ftp 10.0.x.xx
ftp: connect: Connection timed out
ftp> 

I have checked and re-checked iptables conf file and made sure that Port 21 is being Accepted and it is. I have looked this up on the web and decided to try nmap to port scan it and this is what I get for a result:

ryan@ryan-Galago-UltraPro:~$ nmap -PN 10.0.xx.xx

Starting Nmap 6.40 ( http://nmap.org ) at 2014-08-19 15:01 EDT
Nmap scan report for 10.0.xx.xx
Host is up.
All 1000 scanned ports on 10.0.xx.xx are filtered

Nmap done: 1 IP address (1 host up) scanned in 201.38 seconds

Is there anything else that I should do or check for?

UPDATE: I have tried to ping from the virtual machine to my IP address on Ubuntu and have been successfully able to. I cannot ping to my virtual machine from Ubuntu. I have narrowed this down to possibly being a firewall related issue on Ubuntu's side, but why would I be unable to connect from FileZilla?
