arp -f only force for an ip a static mac. so you cant specify 2 mac
addresses or 2 ips in ethers. you can do that using iptables instead.
also, if you dont know the mac associated with an ip then you can ping
it then use arp to see it. if an ip isnt listed in ethers then it can be
used with any mac address.
