Platform: RH 7.0 ISO (Server Install) on ASUS P5-99VM (P233MMX, 128Mb, 20gb HD) Running 'iptables' with any options returns this error message: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. Can't find info anywhere on net. Searched for hours. How can i fix this quickly?
iptables is provided for compatibility with the (future) 2.4.x kernels. kernel 2.2.x does not support iptables, that's why it's complaining. Use ipchains for 2.2.x kernels.
RH7.0 comes with iptables support, but the module loading is not automatic (don't know why). You have to 'modprobe iptables' to make it work.
