I have a TP-Link router running DD-WRT that sits in front of a Draytek Vigor 120 ADSL modem. The ADSL modem is set up in bridge mode, so the DD-WRT router dials the PPPoE. Problem with this setup is that I cannot access the config for the Draytek without unplugging it from the DD-WRT box and plugging a PC in directly.

Is there a way to set up some kind of routing through the DD-WRT box so that I can access the ADSL stats/config from the LAN?
