246 CHAPTER 9 Enabling Client Remote Access with ISA Server 2006 VPNs
3. Enter the username and password of a user that was granted access in the previous
steps.
4. Click the Connect button. The default setting in a new configuration is adequate for
establishing a PPTP VPN connection.
At this point, the client should make the connection to the ISA VPN server and establish
communications with the internal network resources, as specified in the network rules.
Note that the client needs to be outside the network to support this. Check the event logs
on the IAS server and the ISA VPN server if the connection is not successful.
NOTE
Recall that simply establishing a VPN connection to an ISA server does not automatically
grant a client blanket access to the internal network. Firewall and network rules
must first be established, as outlined in the previous sections of this chapter.
Creating Layer 2 Tunneling Protocol (L2TP) VPN
Connections with ISA
The most secure method of setting up VPN access is to utilize a method that combines
both user authentication, such as inputting a username and password, with machine
authentication, which involves making sure the computer the user is using is a trusted
resource.
