[NTLUG:Discuss] Problem with iptables masquerade and FTP

[Neil Aggarwal]

Hello:

I am tryign to use the Redhat 7.1 distribution as a gateway
for my home network.  

I had this working with the ipchains and masquerade in RedHat 7.0,
but with RedHat 7.1, things changed.

Anyway, I tried reading the IP NAT HOWTO and I figured
out that I needed to issue this command to masquerade 
with iptables:
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

Almost everything works fine, but when I ftp to a host,
I get this:

ftp> ls
200 PORT command successful.
550 Cannot connect to 192.168.1.2:1043 - Connection refused.

So, apparently the masquerade is not completely working.

Any ideas?

Thanks,
	Neil.
