I am testing out a wireless mesh design and am using a 4402 wlc with a handfull of 1510 AP's.
I have a number of vlans and IAS authentication configured and all is working well.
The issue I have is with a public access wlan. I have the wlan/vlan configured correctly, DHCP works fine and devices can forward traffic ok. The wlan is set up with no encryption or authentication currently as we want to use the web authentication feature.
I can get the client devices to redirect to the Web Authentication page ok but authentication with the defined IAS radius server fails.
Having had a look in the event viewer of the IAS server it appears to be failing because the NAS-PORT-TYPE is undefined.
So either the 4400 is not sending the NAS type or the IAS is not understanding it.
radius on all the other vlans works perfectly so i cant see why the NAS type is not being provided with web authentication.
Can anyone shed any light on the possible/probable causes?
