Sharing folders over LAN while dialing pppoe through router on windows

I can't seem to get this working. I'd like to have folders shared on the LAN while I have one or more PPPoE connections dialed through the DSL router. The shares are visible if I have no pppoe connections dialed and rely on the main connection dialed by the router. If I dial a pppoe connection my PC becomes hidden to the LAN.
