How do I set multiple IP addresses for ethX

[Michael Oatman <sunsetsea yahoo com>]

Hi all,

Is there a simple config file which I can edit which will let me have multiple IP addresses for a
single interface (eth0 and eth1)?

I tried using Webmin to no avail -- I changed the settings (added eth0:2 and eth0:3 and eth0:5 --
do they have to be sequential or something?) in Webmin appropriately but none of the added
interfaces work after restarting the network, although the IP originally assigned does work.

I restarted the network by /sbin/ifdown; /sbin/ifup which is how I've been doing it before because
there is a iptables problem with the network as bootup and I have to manually start both of them
(iptables or firestarter, and network eth0 and eth1 both hang at bootup, leaving me to
interactively process startup then start the network later).

IP masqing for the WinXP boxen is working using firestarter or you wouldn't be reading this email
sent from one of them at 10.0.0.5.

I'd like eth0 to have four external global IP addresses (A.B.C.241, A.B.C.242, A.B.C.243,
A.B.C.245) and eth1 to have up to 255*255 IP addresses on 10.xxx.yyy.254.

Could I just string these in /etc/sysconfig/network-scripts/ifcfg-eth0 and -eth1 so that 

   IPADDR=aa.bbb.ccc.241 aa.bbb.ccc.242 aa.bbb.ccc.243 aa.bbb.ccc.245

er, probably not, but something to achieve 3 virtual IP addresses?

TIA, Michael
