This is how it basically works for the best of my knowledge: 1. DSL modem gets synchronized with the DSLAM 2. AFTER 1 IS SUCCESSFUL, The router sets up a PPP link with the ISP using the credentials you defined in the router (unless the router has been defined as "Bridge" and then you do it from your PC) 3. The router gets IP address from the other side 4. The router sets default route to the PPP link 5. The router enables masquerading for all traffic coming from the LAN interface, going out to the PPP interface. (like iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE) I hope it's now more clear on why this won't happen with the WAN modem connected on one of the LAN ports, unless you are able to replace the firmware with your own (or it's Linux based and you have SSH access to tinker with those settings...) -- Shimi
