Hi Yoyo,

At least a step I cam further...

I followed the USB Networking instruction.

Do I still have to run
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE echo 1
>/proc/sys/net/ipv4/ip_forward ?

Still wonder if the problem is in the shr installation. I just flashed
freerunner whit shr, to be able to install gentoo. I never properly
used it to phone or something.  The pre-flashed os (om2008?) have not
even had a command line. But there the phone was working. That I
tested.

Well, that's it for today.
Thanks! And good night.

So long, Elmar
