No that flushes the routing cache, not the arp cache.  With the ip command 
you'd flush the arp cache with "ip neigh flush all", you can also cycle 
through all arp entries and delete them with "arp -d address"

Is the router at aware of the network?  If the 
router doesn't know about the local network it will assume 
that the network is not local and try to reach it through the Internet.
