(RADIATOR) NAS subnet problem

[Ayotunde Itayemi]

Hi Hugh,

I know the cause of the problem now. I just remembered some issues on the
mailing list about radiator listening on different IPs etc. My radiator box
has two IP
addresses on the same network card: primary ip of 4.10.10.212 and a
secondary
ip of 6.4.4.12 (not my original IPs :-)
By disabling the secondary interface (eth0:1) and changing the ip address of
the
primary interface on the radius server (RH 7.2) to the one on the secondary
interface
- which is what I normally use to reference my radius installation, I got
the set up to work.

Actually I could move the secondary IP address to a second NIC that is
available on the
Linux box but I am short of ports on the switch that I have the box on at
the moment :-)

I don't know if reversing the order of the IP address with respect to the
network interfaces
(pri & sec) will have any positive effect. On the other hand the box is my
backup DNS server
(listens on pri interface/IP) so I am not sure re-arranging the IPs won't
interfere with my DNS.

Any ideas about this?

Regards,
Tunde Itayemi.

Hello Tunde -

Thanks for sending the files.

It sounds to me like you have a routing problem on the Windows box when
it is on a different subnet. I suspect you will need to add a default
gateway or perhaps a static route so that the radius requests are sent
to the correct place.

regards

Hugh
