Hi, Victor:
Netfilter is the kernel part. iptables is the corresponding
user space part. There should be nothing wrong if you
are using xenolinux-2.4.25, just upgrade your iptables.

I have installed xen 1.2 on a mandrake 9.2 distribution(reading
Xeno-1.2-HOWTO.txt).
When I do xen_nat_enable the error is:
iptables: Invalid argument
iptables returned error; have you build netfilter?
When I compiled the kernel the defaul otion for netfilter was:
Network packet filtering - included
Section IP: Netfilter configuration
Full NAT - included
MASQUERADE - included
At a closer look the error cames from this command:
iptables -t nat -A POSTROUTING -o eth0 -s 192.168.0.0/16 -j MASQUERADE
Thank you
