Hi all,
I'm facing a really strange problem. The setup:
IAS+RRAS on Windows 2k3 server - FW with proxy - FREERADIUS on linux
There are to clients for the freeradius:
- Linksys WRT300N ( 802.1x + WPA2 on wifi )
- Cisco 3750G ( 802.1x on wired port )
The freeradius is configured as a proxy for IAS, and with the Wrt300N and the
wifi it's working fine!
But with the Cisco I'm getting this:
Thu Jan 15 11:19:36 2009 : Error: WARNING: Malformed RADIUS packet from host
[fwproxy_IP]: received 1500 octets, packet length says 1581
Thu Jan 15 11:19:41 2009 : Error: WARNING: Malformed RADIUS packet from host
[fwproxy_IP]: received 1500 octets, packet length says 1581
Thu Jan 15 11:19:47 2009 : Error: WARNING: Malformed RADIUS packet from host
[fwproxy_IP]: received 1500 octets, packet length says 1581
Thu Jan 15 11:19:50 2009 : Error: Rejecting request 21 due to lack of any
response from home server [fwproxy_IP] port 1812
The tcpdump on the freeradius server shows:
11:19:47.389332 IP [freerad_server_ip].1814 > [fwproxy_ip].1812: RADIUS, Access
Request (1), id: 0xdd length: 225
11:19:47.392714 IP [fwproxy_ip].1812 > [freerad_server_ip].1814: RADIUS, Access
Challenge (11), id: 0xdd length: 1472
Sniffing on the FW's inside leg, the IAS sends back Access-challenge for the
Access-Request. What's the matter?
Cheers,
Tamas
