Dobrý den,
Turri (dle lat. skloňování ;-)) se nedaří připojit k ADSL modemu. Současná topologie sítě je, že je ADSL modem v režimu bridge připojen do switche, ve kterém je celá lokální síť a také server, na kterém běží pppd. Toto normálně funguje. Když ale řeknu, že Turris má mít jako WAN PPPoE, připojím ADSL modem přímo do ní, tak sice pppd na turri běží, ale modem to nenajde. při přepojení do původní topologie to funguje spolehlivě.
Co mám zkusit udělat?

Log z Turris (neúspěšný) a serveru (úspěšný):
