Hello, I have configured hostapd 2.5 (did not try other versions) to provide WPA-EAP access. However, when I run either another hostapd process as a radius server on the AP, or run freeradius on another host that has a wired connection to the AP, the (radius client) hostapd does not contact the radius server. I checked this with iptraf, and saw no packet from/to port 1812. I tried to send something using netcat from the AP to port 1812 where the freeradius server is listening, and actually got a response. So I don't think this is a problem of some firewall. Actually I didn't setup any firewall on port 181*, and the AP is connected directly to the computer running freeradius with an ethernet cable. Any hints are appreciated. Thanks in advance! Guan P.S.
