Hi, thanks for your help till now.
I was on vacation and today i tried again to resolve the issue between the FreeRadius and ASN-GW
At the section post-auth of the file raddb/sites-enabled/default i put the next lines
        update "reply"{
                WiMAX-MN-NAI = "%{User-Name}"
                WiMAX-IP-Technology = "CMIP4"
                WiMAX-hHA-IP-MIP4 = "192.168.10.3"
        }
        wimax
        update "reply"{
                WiMAX-MSK = "%{EAP-MSK}"
        }

Now i don't have warnings (Mobile IP keys are generated normally) but WIMAX-MSK is not 64 bytes again..
Below is the log from radiusd -X

  See "man unlang".  You need to use %{EAP-MSK}.

...

        WiMAX-MSK = 0x4541502d4d534b

WiMAX-MSK is not 64 bytes and the ASN-GW doen not accept it...


  It contains the ASCII string "EAP-MSK", which is what you told it to do.

Do i have to make more changes?


  Yes.
