The short way, supposing your wan is secure and your wan interface is eth1: Disable any firewall rules on your centos, service iptables stop chkconfig iptables off try these commands, and if this is working put them in your /etc/init.d/rc.local # enable forwarding of packet between all interfaces echo 1 > /proc/sys/net/ipv4/ip_forward # config masquerading, any packet leaving eth1 will be masqueraded, taking eth1 address for source address. iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE Regards. > > > > > 2008/1/22, Dennis McLeod <dmcleod at foranyauto.com >: > > > I have an IPcop box setup at work.
