WLAN Radius (NPS) authentication fails (since upgrade to UTM 9)

fundinfo
Hi,

since the upgrade to UTM 9 (9.004-34) (HA Mode) we are experincing some problems with our WLAN authentication. 
There is a RADIUS server set up (Windows Server 2008R2, NPS Server, configured as described in the Sophos KB), which worked fine with our devices running V8.***. Since the upgrade to UTM none of the clients is able to connect to the wireless network using WPA2 Enterprise (WPA2 PSK works fine). Nothing was changed on the RADIUS server side and the configuration/shared key, etc was double checked. There are no errors in the NPS log, but the Sophos wireless log shows the authentication process.
 
The error showing up is the following:
802.1X: authentication failed - EAP type: 0 ((null))
802.1X: Supplicant used different EAP type: 1 (Identity)

The part of the logfile showing the error message is attached.


Any ideas?

Thanks.

    Hi,

    @BrucekConvergent: as far as we know this bug affects only radius setups together with IPSec tunnels.

    @POC, Bratwurstengineer and fundinfo: do you use an IPSec tunnel?

    regards,
    Emanuel

    When you say "using an IPSEC tunnel" do you mean using an IPSEC tunnel to reach the RADIUS services (perhaps at some remote site)?
