Hands-On Exercise: Configuring VPN Using PPTP
Windows Server 2008 supports PPTP, L2TP/IPSec, and SSTP. If you followed the exercise
for configuring Remote Access, your server is now set up to receive incoming VPN
connections. You server is configured by default to listen to a number of VPN ports for
PPTP, L2TP, and SSTP. Although theoretical limits exist on the maximum connections
your server can support, realistically your server hardware will limit the actual number
of VPN clients it can support. The default is set to 128 connections each for PPTP, L2TP,
and SSTP. In this exercise, we increase the number of SSTP connections to 256 and disable
PPTP and L2TP for remote access.
1. Open the Routing and Remote Access management console.
2. Expand your server name node and select Ports. Notice how all the available
ports are listed in the Ports details pane on the right (Figure 11-39).
3. Right-click Ports and select Properties.

4. You??™ll see a list of all the devices that RRAS is using. We are interested only
in WAN Miniport (PPTP), WAN Miniport (L2TP), and WAN Miniport (SSTP)
(Figure 11-40).
5. Double-click WAN Miniport (SSTP).
6. Make sure that Remote Access Connections (Inbound Only) is checked and
leave the Phone Number for This Device field blank since we won??™t be using
SSTP over DUN.
