Roteamento Red Hat

Ei pessoal, fiz toda essa parafernalia no meu red hat, no arquivo rc.local, ele pinga a internet e rede interna mas nao roteia. o que falta fazer ai, sendo que
eth0=200.207.45.160;255.255.255.192
eth1=192.168.0.1;255.255.255.0

meu rc.local ficou assim
#!/bin/bash

toucha /var/lock/subsys/local

/sbin/modprobe ip_conntrack
/sbin/modprobe ipt_MASQUERADE
/sbin/modprobe ipt_LOG
/sbin/modprobe iptable_nat
/sbin/modprobe iptable_nat_ftp
