I am using Ubuntu 12.04 LTS.
I am setting up a ftp server using
vsftpd in Ubuntu.
Inside my network the ftp server works perfect, but it does not work outside my network.
Please help me with the firewall rules so i can use my FTP server anywhere.

If your network uses NAT, you will most likely have to use a technique known as port forwarding. To do so, you have to visit your router's configuration website. More information can be found on your router's manual.
