You need to recompile kernel to enable IPTABLES support. I am giving the steps to enable IPTABLES support during kernel recompilation.
Get into the kernel source directory:
# cd /usr/local/src/kernel<version>
# make menuconfig
Select the following option (not as a loadable module)
Networking >> Networking options >> Network packet filtering (replaces ipchains) >> Core Netfilter Configuration >> Netfilter Xtables support (required for ip_tables) and select the all following options as modules.
Networking >> Networking options >> Network packet filtering (replaces ipchains) >> IP: Net Filter configurationS >> IP Tables support
# make
# make modules
# make modules_install
# make install
