How configure firewall with ftp

[Champaka Guruge <cguruge@yahoo.com>]

Hi all

I have configured a iptables firewall (2.4 Kernel). It
has allowed any service form inside and only ssh and
mail from outside.

My probles is, from inside I can not ftp to  outside
server.

When i type ftp command it prompts username and
passwords. but I can not get "ls" output. 

It gives

550 Permission denied
425 use PORT or PASV first


I hope Your help


Thank You

Champaka
