NAT on suse linux 10.0

["amit ash" <ashkadabba@xxxxxxxxxxxxxx>]

Hi,

I have just installed and configured Squid proxy service on Suse 
Linux 10.0. It is working fine but I also need to configure NAT so 
that my users can download their emails in Outlook. To achieve 
that I have added these lines in the "/etc/sysctl.conf"

net.ipv4.ip_forward=1
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -I FORWARD -i eth1 -o eth0 -j ACCEPT

But still the NAT doesnt work on this server. Please direct me and 
thanks in advance.
