Iptables and SNAT

["Jan Kaastrup" <jka@protego.dk>]

Hi list
After a reboot of my RedHat mashine, the NAT part of Iptables stop
working.

I get: "iptables: Invalid argument" when using snat.

My snat rule look like this:
$IPTABLES -t nat -A POSTROUTING -o $EXT_INT -j SNAT --to-source $EXT_IP

I have made all netfilter stuff as modules.

Any hints???

I have tried to recompile iptables - but nothing seems to work - I know
it did before the reboot.
Only thing that has been changed is a static route being enabled, but
this shouldn't make iptables complain:(

Thanks a lot
