I would like to know if anyone has setup an ACS server using Radius to act as a DHCP server. We are
using ACS server version 2.5 and we are trying to let the server pass information such as DNS suffix to the authenticated dial in client. At the moment the router is assigning the ip address with the "ip local pool" command but we can't forward the domain to the client thus the reason to try and make the radius ACS server supply the info like a DHCP server.
Is this possible ? If so can you point me in the right direction.
You may want to try to have the router assign the domain name to your clients. Use the ip dhcp pool [pool name} command in config mode, you can then define your domain name, dns servers, even exclude addresses.
I do believe that this is a new command set in the 12.0 IOS though, so if that isn't what you're running, this may be of no use.
The most recent version of the assigned numbers shows that addresses for DNS servers has been added to the host addresses IPCP can give the PPP client. It does not include the DNS suffix. [excerpts below]
Remember that it does little good to send parameters through IPCP unless the client is prepared to configure its stack with them. Even if you added the parameter to IPCP, the clients would have to use it.
The trend is to use DHCP for these parameters. DHCP can operate over PPP as easily as over ethernet, and can request parameters (which it calls options) even if the client already has an IP address.
One alternative would be if Microsoft's networking software did a DHCP request for the Domain Name Option (15) when it brings up a PPP interface? The solution might be as simple as adding DHCP
(it is just a protocol) to the NAS, or configuring the NAS to relay DHCP requests to ACS which could answer DHCP requests as easily as it handles RADIUS requests.
