Windows Server 2008 supports both IPv4 and IPv6, so you can configure the DHCP
Relay Agent for each of these protocols independently. For example, you may direct IPv4
DHCP clients to one DHCP server and have IPv6 addresses handled by another server.
In this exercise, we configure the IPv4 DHCP Relay Agent to go to our DHCP server.
1. Open the Routing and Remote Access management console.
2. Expand the server name, and then expand IPv4.
3. Right-click DCHP Relay Agent and select Properties.
4. In the DHCP Relay Agent Properties window, add the IP addresses for your
DHCP servers (Figure 11-32).
5. Click OK to save the changes.
6. Right-click DHCP Relay Agent and select New Interface.
7. Select the network interface that is connected to the subnet of the clients that
need to have their DHCP requests relayed, and then click OK.
8. In the Internal Properties window, make sure Relay DHCP Packets is checked
and adjust the hop-count and boot thresholds to appropriate values for your
network (Figure 11-33). Then click OK.
Configuring RRAS Server Properties
At this point, your server is already capable of accepting inbound DUN connections,
provided you have the appropriate hardware listening to your configured modem lines.
The general options for RRAS are actually configured at the server level. If you open
