Hi Ibrahim Ping will not work because NOX routing module does not provide conventional IP routing. You will need to code it yourself.
There is another thread that had similar concern: http://www.mail-archive.com/nox-dev@noxrepo.org/msg02563.html For IP routing to work across subnets: - The IP router should reply to ARP from both subnets - Any pkt with dst MAC being that of the IP router should be fwded to real destination, only after dest MAC is replaced. - For finding the ultimate dest MAC, the IP router should perform ARP request for the ultimate dest IP None of the above is performed by the NOX routing module. If you do manage to develop the code for this, please feel free to mail appropriate modules/code to the list. Thanks Srini.
