the instructions ask "The Rivendell-Mordor Router: what should the default route be?" then tells us to "route add default gw 192.168.3.xxx"
we have already set the default route on Rivendell-Mordor Router in previous steps AND the default route on the Rivendell-Mordor Router would be 192.168.2.xxx.
I think this should actually say: The Mordor Host: what shoudl the default route be?" because the gateway for that host would actually be 192.168.3.xxx and at this point we have not been previously been instructed to set it.
Rich?
