The important thing is that the netmask needs to be 255.255.255.252 which gives you only 4 IP address on that interface and of these only 2 are usable as the others are the network address and the broadcast address. You could have... IPADDR=141.161.111.242 for eth0 IPADDR=141.161.111.241 for 141.161.185.38 interface Broadcast=141.161.111.243 Network=141.161.111.240
