[tlug] routing question

[Botond Botyanszki <tlug@example.com>]

I have set up ethernet over usb for my zaurus so when I plug it into my
laptop I can ssh into the zaurus from the laptop.

The problem is that I cannot reach other machines on the network from the
zaurus. 
I can ping the usb interface on the laptop from another PC and from the
zaurus as well. Can ping the usbd interface on the zaurus from the laptop.
But cannot ping the usbd interface on the zaurus from the PC, I get
a "Destination Host Unreachable" error.

The iptables rules are all flushed just to make sure.
Here are the details attached in a file.

Any suggestions what to try next?
