Hmm, strange, the Telco tells me it is a GGSN 4.0
They also told me it should be type 135

I now tried it here with the parameters as you wrote down but it won't 
work, when I trace in Ethereal I now see the vendor Microsoft with 
attribute 28 (Primary DNS) but the mobile won't get the DNS parms so 
possibly a different implementation on this device of ericsson?

Can any company do what ever they want with these Radius 
implementations? Isn't there a descent standard?

Thanks,
