QUESTION 255
Your network contains a Routing and Remote Access server named RRAS1 and a DHCP server named DHCP1.

If a DHCP server is on the same subnet as your remote access/VPN server, DHCP messages from VPN clients will be able to reach the DHCP server after the VPN connection is established.
If a DHCP server is on a different subnet than your remote access/VPN server, make sure that the router between subnets can relay DHCP messages between clients and the serveryou’re your router is running a Windows Server 2003 operating system, you can configure the DHCP Relay Agent service on the router to forward DHCP messages between subnets.
To configure the DHCP Relay Agent to work over remote access:
Click Start, point to Programs, point to Administrative Tools, and then click Routing and Remote Access.
In the object tree, expand Your_Server, expand IP Routing, right-click General, and then click New Routing Protocol.
