ho configurato un cisco 877w con alice business click impostando 2 vlan per avere un ramo dmz.
La connessione è ok, così come le connessioni da e per LAN, DMZ e Internet.
Ho provato poi ad aggiungere la possibilità di entrare in VPN con VPNClient ma mi succede una cosa strana.
Il client contatta il router, il router mi chiede la password del gruppo sembra tutto normale ma dopo pochi istanti mi dà un frustrante "not connected".
Ho messo sotto debug la connessione e credo che questo sia il punto dove mi indica l'errore:
