What do you see in your /var/log/proftpd.log? Do these connection
attempts actually reach your FTP server?

> Anywhere else I should enable port 21?

You need to make sure a couple of things:

* Your firewall needs to allow connections to port 21 of its public

* Indeed, port forwarding has to work to forward connections on port 21
to port 21 of the actual FTP server machine.

* You need to see whether to use active or passive FTP. Given active
FTP, you need to make sure your client-side firewall does allow inbound
connections on non-privileged port. Given passive FTP, you should
ensure having (a) configured a set of ports to be used for that in your
proftpd.conf (PassivePorts directive) and (b) set up your firewall to
allow connections to these ports as well as forwarding them to the
appropriate FTP server ports.

If you do have any more questions, check [1] for some basic details on
that and/or feel free to ask. Setting up FTP especially across
"consumer-class" firewall/router devices can be a pain...
