Have you assigned an IP address from each of those networks to the corresponding interfaces? Other than that, you just have to set the sysctl net.ipv4.ip_forward to 1. Generally you can set this permanently in /etc/sysctl.conf. Then the Linux router will route among those networks. > Thanks > Kalham -- Kenyon Ralph
