On my home network the main box is Mandrake 9.2. I just booted in to a fresh new 9.2 kernel and noticed that my rc.firewall i have set up (iptables) for IP Masquerading isn't working. I get the following errors when it loads.

iptables: Invalid argument

it's not finding the modules it needs. how do i go about building them and where do i need to put them? also I'm not sure on which line the "Invalid argument" is but I'm pretty sure it has to do with the modules. Or is it just that the version of iptables that comes with 9.2 doesn't work with the 2.6.0 kernel?

Thanks in advance.

Did you build your own kernel?

The Iptables options are in Device drivers -> Networking support -> Networking options -> Network packet filtering (replaces ipchains)

And it is turned off by default?

Yes I built my own kernel. Thanks
I'm looking there and it has
Network packet filtering: enabled
under the IPtables section there it has them all checked to be compiled as modules. (Checking my saved .config in /usr/src/linux-2.6.0) I'm kinda lost now... I'll check my rc.firewall and see if maybe the locations/names are different? hmm.. Thanks for the reply!

The modules should be located here:
/lib/modules/2.6.0/kernel/net/ipv4/netfilter/

/lib/modules/2.6.0/kernel/net/ipv4/netfilters is there and so are all the modules. but it's still giving me the same errors. I even tried remaking the modules/remaking modules_install. guess I'll just wait for a release that comes out with the 2.6 kernel. I really like it but I've got to have the NAT masquerading enabled. Thanks for your help /bin/bash. I really appreciate it. I think it's just a little over my head at this point and I'm going to wait.
