How to Use DHCP to Provide RAS Clients with DHCP Options

ID: Q232703

The information in this article applies to:
  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Advanced Server

SUMMARY

You can now use the DHCP Relay agent with RAS to provide DHCP scope options to RAS clients. The RAS client continues to receive an IP address from the RAS server, but may use DHCPInform packets to obtain WINS addresses, DNS addresses, domain names, or other DHCP options. DHCPInform messages are used to obtain DHCP scope option information without getting an IP address.

NOTE: Sending the domain name using DHCPInform is of particular importance because PPP does configure this information.

DNS and WINS addresses received using DHCPInform override address obtained from the RAS server.


MORE INFORMATION

To configure the DHCP Relay Agent to work over RAS:

  1. From the Routing and Remote Access Administrative Tool, right-click General under IP Routing, click New, and then click Routing Protocol.


  2. Click DHCP Relay Agent.


  3. Configure the IP addresses of any DHCP servers from the DHCP Relay Properties page.


  4. Right-click DHCP Relay Agent, and then choose New Interface.


  5. Click Internal. Internal represents the virtual interface connected to all RAS clients.


NOTE: The DHCP Relay Agent must be installed on the RAS server but cannot be run on the same system as the DHCP server.
