- By default, Network Tallahassee configures DSL modems as routers without bridging.
- PPP authentication is handled by the DSL modem. No other devices on the LAN should be configured to handle PPP authentication.
- Network Tallahassee rarely configures DSL modems as bridges because doing so eliminates our ability to perform any kind of diagnostics when there are potential connectivity issues.
- Bridged modems are non-routing media converters; all built-in routing and PPP authentication capabilities are disabled (or non-existent on some older modems, such as the Efficient Networks SpeedStream 5260).
- PPP authentication must be handled by a device on the LAN behind the DSL modem:
- Router acting as a gateway between the DSL modem and the rest of the LAN
- Computer connected directly to DSL modem or connected to network switch/hub that is connected directly to the DSL modem
