access-list duplicate su configurazione VLAN

[Pictor]

Sto cercando di usare il wizard del PDM per creare una VLAN.
Vorrei che dall'esterno sia possibile collegarsi alla LAN grazie a degli account user/pass.
Ho configurato tutto in L2TP (per non obbligare ad usare il Cisco VPN Client).
Però quando vado a completare la configurazione mi restituisce un errore:

[OK] no vpdn group L2TP-VPDN-GROUP
[OK] vpdn group L2TP-VPDN-GROUP accept dialin l2tp
[OK] no vpdn group L2TP-VPDN-GROUP ppp authentication pap

Non riesco a trovare molto a riguardo e non capisco cosa crei il conflitto.
Potete darmi una mano?

Fai un "sh access-list inside_outbound_nat0_acl" e vedi che ti da
