I have a v2.9.42 MT Router on a private subnet behind an ADSL router that performs NAT.
I have configured a Hotspot on a Virtual AP and pointed the RADIUS Client at an external RADIUS Server hosted on a public address at a hosting centre.
Using radtest I can authenticate locally on the RADIUS server, I can also authenticate OK from a PC connected to the same subnet as the MT Router.
The RADIUS server is running in debug mode, when I connect to the HotSpot I'm prompted for Username and Password, these are entered, but "RADIUS server is not responding" is the error returned. There is no debug information at all on the RADIUS server, i.e. no attempt to connect. I've tried rebooting the router a couple of times, but it seems to refuse to send packets to the RADIUS server.
I've tried adding the IP address of the RADIUS server to the Walled Garden, but this makes no difference.
I can PING the RADIUS server from the MT router.
I've followed everything to the letter in the Wiki example, but I'm out of ideas.
Regards
