[cisco-nas] Sending Radius requests from a different interface

[Wayne]

Hello,

I have a 3640 making ppp connections at a remote location. The radius
request come from the serial interface going to Sprint. Sprint has decided
to not route any packets to there serial interfaces. So my radius requests
reach my radius server coming from the serial interface of my router but the
response packets never reach my router. How do I tell the 3640 to send the
radius requests from the ethernet interface ?
