A proxy server is a Lunar instance acting as a secure RADIUS gateway to NebularStack. Whether on a physical host, virtual machine, remote, on-premises, or within the NebularStack distributed cloud, it is a crucial component of your authentication, authorization, and accounting service. One proxy can run multiple instances of proxies to different Virtual AAA instances.

The proxy serves as a bridge between NebularStack backend systems and your radius client (NAS/BNG) nodes.

By default, we assign 3 proxy instances per virtual server.
