Block diagram of the network configuration. This is the configuration used with the Cisco 675 and a routed subnet. It is my desired configuration. Currently broken by the firmware in the Cisco 678.
Block diagram of the current network configuration. In order to upgrade to the faster DSL connection I needed to switch to a DMT capable DSL modem. I acquired a Cisco 678 to replace my Cisco 675. After switching to the Cisco 678 I could not make the routed subnet configuration function. The firmware is different and, apparently to me, buggy. The latest available firmware CBOS v2.4.6 has been installed.
