IP setting for supplicant

[matt morris]

Hi, I have been having problems getting the supplicant to gain internet 
access through my freeradius + Dlink DWL900AP+ AP + WinXP Supplicant(Linksys 
WirelessG PCMCIA card) setup. I'm using EAP-MD5 authentication. Freeradius 
has granted Access-Accept, but the supplicant doesn't get an ip (I've added 
the framed-IP-Address and Netmask attribute to the users file). Basically my 
setup is like this:

(1) The Dlink AP (with static internal ip, default gateway and DNS to 
router's internal ip, DHCP disabled) is connected to a Router (with WAN ip, 
port 1812 forwarded to the AP's ip, DHCP enabled - ip range covering Ap's ip 
and supplicant's framed ip);
(2) Redhat 7.2 with Freeradius 0.9.3, with its own WAN ip; in the user file: 
Framed-IP-Address =192.168.0.105, Framed-IP-Netmask = 255.255.255.0, 
Framed-MTU = 1380
(Actually a question: Does the user's framed-MTU have to match that of the 
AP's?)
(3) WinXP Supplicant, set with static ip 192.168.0.105 and netmask 
255.255.255.0, Default gateway and DNS to router's internal ip.

Both freeradius' and the AP's log shows the authenication was successful, 
but the supplicant was not supplied with an ip (just 0.0.0.0). I've tried 
getting rid of router from the setup (un-setting the Ap's default gateway 
and DNS while setting the supplicant's to the internal ip of the AP), but 
still no luck....

I know this isn't exactly a freeradius question, but I'd really appreciate 
it if someone in this list could help me out. Thanks in advance!
