MS VPN through SonicWall TZ-170...

I would assume you would use IPsec that's on the Win2K and up O/S(s) (host) the server and (client) the user machine -machine to machine or software to software VPN connection.

You may need to do some more research I am sure you can use Google to find out the information you need.

It sounds like what you want to do is to allow a VPN 'through' the SonicWALL 'to' a server located on the private (protected) side. And by reference to port 1723 which is used by MS PPTP, I am almost certain that is what you want to do. If so then you'll need to ensure that you've defined the Firewall policy to allow PPTP (TCP port 1723) inbound from the 'net to the PPTP server and you should be good to go.

Don't forget GRE - it won't work without GRE. Many firewalls have a PPTP Rule that you can enable. You also need to make sure that both sides have different subnets or you will have problems.

That is true of many firewalls. Fortunately the SonicWALL will automatically allow this protocol through if the predefined PPTP service is added to the rules. At least that is my understanding of the SonicWALL.
