I didnt know about the /etc/ethers file. Is it possible to assign two ips for a single mac in that file and a single ip for two macs ? e.g. ip1 <mac1> ip2 <mac1> and ip3 <mac2> ip3 <mac3> Besides, if i leave out some of the clients from the /etc/ethers file (I dont know all mac addresses right now) , will it create problems for those who are not included ?
