I got similar problems with several targets, including DNAT and SNAT !!!
How do I solve the problem ? Simply recompiling iptables with the newer
kernel running !!
And, as usual, you should check if your kernel is really compiled with
ipt_owner support. You can do that with the command 'modinfo ipt_owner'. If
it shows ipt_owner module informations, that's fine. If it shows 'no module
by that name found', your kernel wasnt compiled with that iptables module
option.
Sincerily,

Subject: problem with "-m owner" in kernel 2.4.20
Can anyone tell why the below shown line fails when running kernel version
2.4.20 but not when
running kernel 2.4.19.
/usr/local/sbin/iptables -A OUTPUT -o eth0 -m owner --uid-owner root -j
ACCEPT
iptables: Invalid argument
