How do I put 802.1x authenticated machines to an existing subnet.

[Guest]

I ran into the following problem when I tried to add wireless machines to an
existing subnet.

Setup:
Windows 2003 server with 2 NICs, one is connected to "network A" (obtains IP
from a DHCP server), one is connected to an AP. It's also a wireless RADIUS
server (IAS).

I want to add all machines on the AP side to "network A". The problem I have
now is that if I bridge these 2 NICs, I won't be able to do 802.1x auth,
because the AP needs to know the IP of the IAS, but the IP is dynamic
(obtained from DHCP server in networkA).

Is there another way to do this? Thanks.

While the above it possible, it sounds like it might be a typo.

Is the AP (access point) a Windows or Linux machine? If not,
then it isn't likely a "RADIUS SERVER" but rather a RADIUS
CLIENT.

Usually an AP is a RADIUS CLIENT.

I want to add all machines on the AP side to "network A". The problem I

Give the IAS a manual OR DHCP assigned RESERVATION
so that the address will remain (effectively) static.
