Goodday,
Is it possible to use a radius server that is not accessible trough the internet?
Currently I have a HUB with three SPOKES. The Hub is connected to a LAN with port 2. The next hop is a customer FW through which all traffic is routed. Behind that firewall is a raduis server, 10.11.1.7 & 10.11.1.8 port 1500 (fictional). Both adresses are reachable via ping.
According to the Access Controle page the radius server should be accessible from the internet. That is possible.

Is there another ways clients of the SPOKES can log on via radius?
