We saw the same: smart phone works fine, UMTS stick fails to establish data. You might be onto the reason there, would be great if you could help us resolve this! > Has anybody successfully used an UMTS-Stick with ggsn? > How can I tell ggsn to send his IP-Adress, which can be used by pppd as "remote IP address"? > Are there special options for pppd which I have to use? I don't really know and would have to look into it in detail. It would be great if you could try to understand what's going on from traces and/or openggsn code and/or openbsc code... Maybe we somehow send the wrong or incomplete configuration and maybe smart phones have some magic to work around it, which UMTS sticks don't? ~N -------------- next part -------------- A non-text attachment was scrubbed...
