SO HOW! iptables: invalid argument

["John Paul" <john@xxxxxxxxxxxxxxxxxxxx>]

Hello Folks,

Just want to find the real answer with this. sorry but ans to google is not
clear for me. I did upgrade my iptables to iptables-1.2.9rc1.tar. steps
done;

--> installed new iptables source (iptables-1.2.9rc1.tar)
        - make KERNEL_DIR=/usr/local/linux
        - make install KERNEL_DIR=/usr/local/linux

--> applied POM (patch-o-matic-20030912.tar) to my latest kernel
(linux-2.4.22.tar)

--> recompile the kernel
        - make dep; make clean; make bzImage; make modules; make
modules_install
        - all went fine

--> reboot the machine

all went fine but when NAT/MASQUERADE is used, i got this "iptables: invalid
argument"

anything i missed?

Thanks.
