Hi all,

I'm juste a newbie in iptables ;)  My problem is, i have a linux box routing my DSL
connection, i set these rules:

iptables -A FORWARD -i ppp0 -o eth0 -j ACCEPT
iptables -A FORWARD -i eth0 -o ppp0 -j ACCEPT
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -A FORWARD -j LOG --log-prefix "Firewall: "

== Great, i have acces to thet NET ! ==

I have also a machine (192.168.0.50) in my local network running an FTP client this
one runing an identd daemon (port 113) to access to an FTP server on the internet, i
have added this rule

iptables -t nat -A PREROUTING -p tcp --dport 113 -i ppp0 -j DNAT --to
192.168.0.50:113

But my FTP client tels me:

[11:51:58] PORT 192,168,0,50,13,161
[11:51:58] 200 PORT command successful.
[11:51:58] LIST
[11:52:02] 425 Can't build data connection: No route to host.

Any help would be appreciate ;)
