This is what i get, i'm pretty new with iptables but i really would like to
use it.

Greetz!

O.k., I use Red Hat and kernel.org kernels and modules, but it seems
*very* strange to me that Mandrake should use gzipped modules. Maybe it
does, who knows? Because my basic iptables modules are compiled into the
kernel, I couldn't try gzipping iptables modules, but I put my precious
Conexant modem modules on the line for you, gzipped them and tried to
load them. 

Well, of course I couldn't. So I unzipped them again and hey presto,
good as new. 

do: 'cd /lib/modules/2.4.18-6mdksecure/kernel/net/ipv4/netfilter'
'mkdir ../netfilter.bkup' 
'find . | cpio -pumv ../netfilter.bkup' 
'gunzip *' 

Then try your iptables load again. 

If it still doesn't work, change the dir. contents back to what they
were: 
'gzip *' 

It still won't work, but you won't be any the worse off. 

Remove cd /lib/modules/2.4.18-6mdksecure/kernel/net/ipv4/netfilter,
whatever happens.

***NO***!

Remove /lib/modules/2.4.18-6mdksecure/kernel/net/ipv4/netfilter.bkup and
contents!

Humble apologies :-(

There is a compile-time option to modutils (modprobe, insmod, et al) that
permits gzipped kernel modules.  The INSTALL file from modutils-2.4.16
has this to say about it:

    [configure options]

    --disable-zlib          Handle gzipped objects?  Default is no.
                            You probably only need this if you are booting
                            a small root filesystem and the filesystem is
                            not compressed itself.

I know Slackware 7.1 and 8.0 enable this feature.

Ah. Well then, Philippe's possibly suffering from the well-known
ipchains syndrome. lsmod would show this.

The solution is remove the ipchains modules (if they're not compiled
into a monolithic kernel) and substitute iptables.

Under Red Hat, up to v7.2, anyway, it was standard to start up ipchains
instead of iptables after a fresh install. All the iptables stuff had to
be done by hand, i.e. stopping automatic loading and enabling automatic
loading of iptables.
