I'd've thought I could become root and do "nano -w /sbin/ifconfig" -- if I knew what to add -- but what I get is four hundred-odd lines of gibberish, with a note at the bottom saying it's converted from Mac format, whatever that is.
That's the wrong approach (and wrong file to be editing.) All network interface (cards) configurations are in /etc/sysconfig/network-scripts/ and gateway information is set in /etc/sysconfig/network - leave ifconfig alone. :) Try my previous suggestion please.
