Hi,
I have downloaded iptables-1.2.9 from netfilter.org and installed using make and make install commands after compiling the kernel with network packet filtering (replaces ipchains) option having value yes
also the settings under IP netfilter configuration are.
connection tracking module
FTP, amanda ,TFTP,IRC support no
IP tables support (required for filtering/masq/NAT) module
Packet filtering module
full NAT module
Redirect support module
ipchains 2.2 style support no
ipchains 2.0 style support no
then i compiled kernel and rebooted machine
But when i issued the following command
>
> iptables -A INPUT -s 127.0.0.1 -p icmp -j DROP

Did you compile a new kernel without updating iptables ?
If so, compile a new iptables (1.2.9) too.
