We just set up a new SonicWALL TZ210 Wireless-N firewall. I am a bit comfortable with firewalls, but this device is very intricate to me as it is nice. I have the VPN options enabled according to the default configuration, per Sonic's online tutorial (also, very nice). I am confused with how authentication seems to be working and how IP addresses are being handed-out.
If I make a VPN connection from a Windows 7 box, off of the LAN, through the firewall, with the built-in Windows tools, I can connect to resources and devices. For this I use the SBS domain username and password or a local user and password, specific to the SonicWALL device. The same can be said for a Mac with the built-in OS X tools. On the Mac I log in with the SBS domain username and password, no sweat.
SonicWALL has their own GlobalVPN client software package. When I use that on Windows 7, I can make a connection, but that is it. No IP address seems to be applied to the Virtual NIC, Sonic's VPN client creates on Windows. I do have it set so that DHCP will provide an IP address to VPN clients in the firewall's config. The firewall is the VPN server. I also have to use the local account on the firewall to get in. I don't even think it considers domain logins.
How can I configure it so that Active Directory authenticates the VPN users? Is the SonicWall client software needed?
