    Andrew,

     Yes, I can ping from linux the ip 10.2.2.1. I have a fedora installed,
 with eth0 and eth1. The interface eth0 is configured with ip 192.168.0.11
and is used for adsl based internet connection. The eth1 is used only for
supplying the ecos application with a real ethernet board. It is activated
only when the ecos application is started (with the --io option).
I have tried using ethertap, but got the same results.
