The RADIUS proxy IPs are the source IPs of the RADIUS packets the User VPN gateway sends to your RADIUS server. Therefore, your RADIUS server needs to be configured to accept authentication requests from the RADIUS proxy IPs. If the RADIUS proxy IPs field is blank or none, configure the RADIUS server to accept authentication requests from the hub's address space.

This is mandatory to make sure the gateway can talk to the RADIUS server and vice versa.
