Hi, I'm using an FC3 box as a router and need to NAT some addresses. I can add those addresses with "ip address add 10.0.0.1 dev eth0" but this isn't persistant. I can add alias config files (e.g. ifcfg-eth0:1) but these appear to have to go in three places: /etc/sysconfig/network/devices, /etc/sysconfig/network/profiles/default and /etc/sysconfig/networking-scripts. I haven't got X on this box so I'm doing this at the shell. Can anyone tell me: 1. What's the recommended way to make ip aliases persistent? 2. If I have to use alias ifcfg files should there be three copies? It seems wrong... Thanks in advance, Leon...
