iptables question for the experts

[Dan Coutu]

I'm trying to troubleshoot what seems like it ought to be a simple 
iptables configuration. Here's the goal here:

The server has a cron job that periodically uses ftp to fetch from a 
remote server an updated script to be used for doing backups.
ftp is configured to use passive mode.

I am expecting that following line opens traffic to the remote server on 
whatever port passive mode ftp chooses to use:

-A INPUT -s 64.39.2.176 -p tcp -m tcp --sport 1:65535 --dport 1:65535 -m 
state --state ESTABLISHED -j ACCEPT

The next line immediately follows it in the iptables config file and it 
allows basic ftp traffic in the first place.

-A INPUT -p tcp --sport 21 -m state --state ESTABLISHED -j ACCEPT

When I use wget to test the fetch operation I see it establish a 
connection successfully, go into passive mode, and time out.

Any idea what I'm doing wrong here?

Thanks in advance,

Dan
