Really strange problem, we've got a client with a Buffalo Linkstation LS-WV2.0TL/R1 NAS, the internal clients can access fine.
They've also got a Draytek 2820 router where i have set up a PPTP VPN, i can connect to the VPN fine and can access everything on the Network except the NAS. They've got a user now working from home and needs access to the files on the NAS.
I've upgraded the firmware on the NAS to 1.64 and also the firmware on the router to 3.3.7.3
I really cant figure it out and need to get this resolved ASAP.
Any help would be appreciated.
Thanks in advance.
have a quick read here as well, it is for a qnap but the principal should be the same
