Cannot access NAS over VPN

Hi all.
We have a Buffalo NAS connected to our network but it cannot be accessed via Windows VPN. I can ping the device by IP but cannot browse to it by IP or hostname, I cannot get to its http login screen either so that eliminates any permission errors. I have ran a tracert and it as no problem seeing the device. The gateway address is correct on the NAS and the VPN connection. The only thing that seems to be a bit different is that DHCP is set up on their mail server and Routing & Remote Access is set up on their DC, I don't know why this is it was already like that before I took over. I don't see why that would be causing an issue though as both servers are on the same local network and are visible over the VPN.

This is potentially a firewall issue. can you confirm that the Scope of IP addresses assigned in RRAS are permitted access to internal resources. It maybe that the firewall is locking down access to only selected resources but allowing ICMP through for ping testing.

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Try Disabling the Routing and Remote Access Service, then Re-enable it.

ncomper we have a Mikrotik that has no web interface and is configured with Telnet (another think I didn't know this place), I'll check out your link shortly.
Iruiz52 unfortunately that made no difference.
In the Routing and Remote Access General Tab,

is  the "Router" Check box checked and the "Local Area Network (LAN) routing only" selected?
