Proxy of accounting message

[Ashwin Gobind]

Thanks nick.  However when I proxy the message, the
message-authenticator field has an <INVAILID TOKEN> (see trace below).
Why is this


Sending Accounting-Request of id 1 to 10.113.46.170:1813
        Acct-Status-Type = Start
        Service-Type = Framed-User
        Called-Station-Id = "vlive"
        Framed-Protocol = GPRS-PDP-Context
        Framed-Protocol = GPRS-PDP-Context
        Acct-Delay-Time = 5
        Calling-Station-Id = "27829800729"
        NAS-Identifier = "GMC-GGSN0-13-2"
        Acct-Session-Id = "20050529"
        User-Name = "27829800729"
        User-Name = "27829800729"
        NAS-Port = 6000
        NAS-Port-Type = Virtual
        NAS-IP-Address = 10.111.14.46
