Hi Eddie, Can I ask what reason you are trying to get all your workstation's traffic to traverse your server? I would have thought an easier option for you, if it meets with your requirements, would be the following: + Router has a static IP address of 192.168.1.1 + Router has DHCP disabled. + Server's eth0 has a static IP address of 192.168.1.2 + Server's eth1 is disconnected and no config applied to it. + Server is configured to give out addresses by DHCP with 192.168.1.1 as the client's default route (and DNS, depending on your setup). + Clients then receive their IP address and other network information from the server, but all traffic that is not specifically *for* the server goes via the Router.
