[Router]Error met inloggen via PPTP

[Verwijderd]

Als ik met mijn edimax router (BR-6524K) een PPTP verbinding wil maken met mijn speedtouch adsl modem (verbonden met kpn adsl) dan krijg ik telkens devolgende error:

Ik heb geen idee wat er verkeerd gaat, het modem staat op mode:
PPPoA_to_PPTP,no-NAT,DHCP (via een speciaal tooltje van speedtouch geconfigureerd)

Vervolgens heb ik de router op PPTP gezet, mijn username en wachtwoord ingegeven en als gateway 10.0.0.138 ingesteld.
De MTU waarde staat op 1392 (door router zelf gekozen) en connectiontype: continue. Ip adres verkrijgen staat op automatisch.

Wat doe ik hier nu verkeerd, mijn username en wachtwoord zijn 100% correct.

Ik snap er werkelijk niets meer van.
