[itdiscuss] PPTP VPN

[Dayron Daugherty]

We use win2k3 RRAS for VPN (both PPTP and L2TP/IPSec as we phase out
PPTP). It is on a member server on the LAN accessed via NAT. It is a
Hyper-V VM.

So you would open up the AD ip ports from the DMZ to the LAN so that the
VPN client can authenticate?  How do you get the client to tunnel from
the DMZ to the LAN so that the client can gain access to LAN services?
Usually you setup RRAS in Windows for PPTP, so would you use the RRAS
server as a router as well, with two NICs?  Finally, if you set it up as
a virtual machine, where would that machine "actually" reside in your
ESX farm?

We use Kevin's method of having a separate server (except for the DMZ
part) and the PPTP endpoint server is a virtual machine so there wasn't
any additional hardware outlay.

Any port you have forwarded from your firewall to a domain controller is
a direct attack vector into your domain controller, and thus into AD.
If you have it going to an independent server (either member server or
workgroup), at least you have another step in the process.  They have to
take significantly more control of a server to use it as a jumping off
point to the rest of your network than they do to gain some piece of
data residing directly on the server.  

Even better, stick it in a DMZ, and then only open the ports users will
really need between the DMZ and the LAN.

Just wondering, if I setup a PPTP VPN server on a domain controller, do
you think that is anymore insecure than setting it up on an independent
server?
