dyndns.org domain in Clients.conf

[black devils]

Hi,
I have created one hotspot with a openwrt router and chillispot. I use a
remote server radius (freeradius) for authenticate users of hotspot.

I have inserted in clients.conf Ip of the router:

clients 82.256.52.11 {
           secret = testing123
           shortname = test
}

With this configuration all working fine but unfortunately router has a
Dynamic Ip therefore a can't use its Ip in clients.conf

Thus i try to insert a dyndns domain of the router in clients.conf

clients router.dyndns.org {
           secret = testing123
           shortname = test
}

but with my displeasure freeradius doesn't recognize client.

Same suggestions??

Thanks
