Hello, we're trying to develop a 3rd party software that runs on the N900 and talks to the modem. To make developing more efficient, we try to forward the modem via USB and develop on a PC. For some reason we can't seem to get the phonet0 -> upnlink0 forwarding to work. tcpdump shows our request packets sent from the PC arriving on upnlink0, but nothing responds. Apparantly there is a missing link that connects phonet0 to upnlink0. The software works fine directly on the device, however it would be helpful to get forwarding work as well. Note that running Maemo the forwarding works. What are we missing? Thanks, M. Lauer.
