I am currently running a ftpd server, but whenever someone log on.. it tries to broadcast on it's internal IP address, and not the external internet IP.. Please let me know if you guys have any suggestions

What do you mean by "broadcast"?

When the ftp client sends a request to the site, you can see the log, and the ftp server(or client) is actually trying to send requests to the internal network ip.

See where it refers to the 192,168,0,100.... That's the internal ip address, instead of it's given internet ip address.
