Nat iptables problem

[fahadabdillahi]

i Configured Dhcp server and NAT server together in one server Then DHCP server is working The clients autamatically receive DHCP from the server. then The iptables are not working and I used this commands to configure The nat.
iptables --flush
iptables --table nat --flush
iptables --delete-chain
iptables --table nat --delete-chain
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables --append FORWARD --in-interface eth1 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward
service iptables restart
That is my problem The NAT isnot working and is not translatining inside local ip

Are these the complete firewall rules or are there more?
