Hello, Freeradius team and users community! First of all thanks to all creators of FreeRadius! It makes a lot of people happy ) I use FreeRadius 3.0.9 builded from a source on CentOS 6. Everything is fine. But I still can't find some details in documentation. So I need short comments to clarify. My pain. I have about 800 NASes in our network and all of them is home servers (CoA servers) (no redundancy due to small areas for each NAS). I do proxy CoA from my network control server (CoA client) to NASes that same time are CoA servers (Cisco WLCs) and configuration below works with small trick but as I expected. I named my home server pools same name as "IP" address and it helps me to avoid additional operations, it's good anyway. My question is if I have any chances to simplify configuration and avoid to write 800 home servers and home server pools (each pool still one server unfortunately)? I understand that templates technique may simplify home server sections little bit, but I still need 800 home servers and 800 home server pools? :( I've tried to use clients.conf and derive home servers from that section as announced in 3.0.7. It would simplify but I can't proxy to such kind of unnamed home server (or I can? This is what I didn't find in any docs too. Sorry). As I understand that NAS and CoA server can be same in case I add section in clients.conf.. If it possible to identify this CoA server somehow and send proxy packet to exact server (in my case IP same as NAS IP) it would be nice? 1. Could you please tell me if there is a way to send proxy packet to such unnamed home server (derived from clients) based on IP of my NAS? I've tried to use Packet-DST-IP-Address = "%{NAS-IP-Address}" together with Packet-Dst-Port = 1700 or without it, but seems it doesn't work. Freeradius in debug writes random port number and message like "home server 10.56.33.174 doesn't exists". Later I read in docs that I can't add name to such unnamed home servers so I can't use such home servers in combination with pools (for example) and than use Home-Server-Pool := "%{NAS-IP-Address}"... 2. Is there any way to use something in coa section like update control Home-Server := "%{NAS-IP-Address}" or some other options to proxy CoA packets to NAS/CoA server? Have I missed some important part? Sorry in advance if it is awkward moment. Thank you in advance for your help!
