Problem to access FTP server

[Mahabub Basha]

Hi all,

I am a newbie for freebsd. I am using freebsd 6.1. I have some problem to
access ftp server through external ip behind a pf firewall.

I can access my ftp server through active mode , but not working in passive
mode.

My ruleset file is in the following:

======================================================================
pf.conf
======================================================================
lan = "port2"
wan = "port1"

# User BiNAT Rules
binat on $wan from 10.0.0.10 to any -> 172.16.1.10

# User RDR Rules
rdr on $wan from any to 172.16.1.10 -> 10.0.0.10

# User Filter Rules
pass all

=========================================================================

my lan ip address is 10.0.0.10 and my wan ip is 172.16.1.10

I just put above three rules. And run my ftp server using inetd.

I used core-ftp client in windows xp to connect my ftp server machine , in
active mode its working fine.

But in passive mode its not working.

Before i asked this problem here, i read the following links and try out the
same. but its not working.
