I've had this type of problem a long time ago with a Lucent ORU. It did it because ORU was setting up the ISDN interface as "unnumbered" to the ethernet interface. When I changed the ethernet interface to the static IP address it worked fine. I think that's what it was anyway.

He also needs a subnet routed to him. I have it set up in Radius ok, but we're having a problem with it. When he sets the ISDN router to NAT with his LAN on non-routable addresses, everything works ok. When he sets his LAN on the assigned subnet and disables NAT on the router, he gets dropped before authenticating when dialing up. Any ideas why disabling NAT would prevent it from authenticating?
