Configuring Remote Access Configuration
Many of the options associated with VPNs in ISA Server can be found in the Remote
Access configuration dialog box, accessible via the Select Access Networks link in the Task
Pane. The dialog box invoked via this link, shown in Figure 3.28, allows for the configuration
of Remote Access properties specific to VPN access, but not necessarily specific to
clients. These include the following settings:
. Networks from which VPN clients can connect.
. Address assignment properties, such as automatic VPN client IP address assignment
via the Dynamic Host Configuration Protocol (DHCP).
