How do I set up Radius Tunnelling with my Bay Annex Server?
When a tunnelling user dials into the Annex, the Annex will first authenticate the user@realm with Radius and Radius must return the tunnel configuration options with Annex-Local-Username, Annex-User-Server-Location, Tunnel-Medium-Type, Tunnel-Server-Endpoint, and Tunnel-Type. This information tells the Annex how to set up the tunnel, and the name of the user to reauthenticate (with Annex-Local-Username). The Annex will then set up the tunnel and send a second Access-Request for the username specified by Annex-Local-Username. Radius should reply with the normal PPP radius reply. There is an example Radiator configuration file in goodies/annex.cfg that shows a neat way to do this.
