I am running wackamole on a set of dual-homed machines. They have a "backend"
interface with a private IP (which are free), and a frontend interface with a
public IP (which aren't free). I'd like to be able to use basically all of my
public IPs as VIPs -- is this possible?
My wackamole.conf specifies:
eth0:1.2.3.4/27
eth0:1.2.3.5/27
(public IPs), and my spread is configured to use the backend network for its
communication. Everything works fine if the eth0's are configured with some
other public IP at startup.
When I tried not starting eth0 at startup, wackamole correctly assigned a VIP
to eth0, but did not bring the interface up.
When I tried assigning 0.0.0.0 to eth0 at startup (meaning the OS brought it
up), wackamole again correctly assigned a VIP to eth0, but on a failure
(wackatrl -f), brought the interface down and refused to bring it back up on
recovery (wackatrl -s).
The only solution I can envision is to assign private IPs to eth0 at the OS
level, and let wackamole add its public VIPs as aliases to that. That seems
like a pretty gross hack, though. Is there any other way?
Incidentally, since I didn't say so on my last posts -- Wackamole and spread
are great stuff. When wackamole gets accepted into Gentoo I'll do a writeup
on the Gentoo wiki.

Static IPs required?
