Problems with pppoe and nat

Problems with pppoe and nat

[Damphyr]

I am having problems setting up NAT for my home LAN.

I get the following:

frigorifero root # iptables -v -t nat -A POSTROUTING -o ppp0 -j 
MASQUERADE
MASQUERADE  all opt -- in * out ppp0  0.0.0.0/0  -> 0.0.0.0/0
iptables: Invalid argument

ifconfig gives me:

eth0      Link encap:Ethernet  HWaddr 00:E0:29:09:C0:03
           inet addr:192.168.1.254  Bcast:192.168.1.255  Mask:255.255.255.0

           RX bytes:934 (934.0 b)  TX bytes:664 (664.0 b)

and iptables says:

frigorifero root # iptables -h
iptables v1.2.7a

My PPP link is a DSL line, I use rp-pppoe and I up it using adsl-start.

Can anyone tell me what am I doing wrong?
Thanks,
V.-
