Hi,
Tech calls in and say that he can't get an appliance working in the field. I ask him what secret he's using and the IP address of the appliance. I want to be able to be locally logged onto the radius server and use radtest/radclient/rad???? to be able to query radius asking "If I was IP, and I gave you SECRET, would you authorize me?".
So I want to be on 1.2.3.4, but say I'm on 3.4.5.6 . Right now, If I say I'm on 3.4.5.6, it still wants the secret for 1.2.3.4 .
you want to spoof the source address? tricky. one 'easy' way to do this would be to create a local VPN/GRE tunnel on the linux box under which you could emulate a remote link. configure freeradius to also listen on that virtual address, run the radclient with the destination being the end point of the VPN - the linux routing tables would then come into play. you'd have to reconfigure the VPN end addresses etc each time to emulate an outside world link...but it would work. alan
