FTP Serving

• sudo apt-get install proftpd

At this point, any user with an account on the LAN can access the machine via ftp.

Accessing FTP through NAT (pfSense here...)

• sudo vi /etc/proftpd/proftpd.conf

Lines 51 & 56 need to be un-commented & edited

Choose an available range of ports for PassivePorts.

Set MasqueradeAddress to either the WAN address of your firewall or it's FQDN.

Then create 2 port forwards, one specifically for port 21 (FTP) & one for the the range chosen in PassivePorts.

Managing the FTP server

• sudo service proftpd restart
