DMZ interface managed by LVS

[Pietro Ravasio <pietro.ravasio@xxxxxxxxxxxxx>]

Hi,

I know i could try to realize this trick by myself... But maybe someone has 
realized it already! :)
I use two LVS servers for firewalling purposes too:

                        ROUTER
                Ethernet 0      Ethernet 1
                1.2.3.127       1.2.3.126
                255.255.255.128 255.255.255.128

        Firewall 1 (active)             Firewall 2 (standy backup)
        eth0   1.2.3.1                  eth0 1.2.3.2
        eth0:1 1.2.3.3
        eth1   1.2.3.253                eth1 1.2.3.254
-!!->        eth1:1 1.2.3.252
        eth2   172.16.0.1               eth2 172.16.0.2
        eth2:1 172.16.1.254

                            DMZ
                        1.2.3.128/25

Subnets:
        "Front":      1.2.3.0/25
        DMZ:            1.2.3.128/25
        Localnet:       172.16.0.0/23

I would like DMZ to be able to have 1.2.3.252 as its default gateway (if i 
set 1.2.3.253 _and_ 1.2.3.254 on DMZ hosts, I have routing problem when the 
first one is unavailable (because its entry is not removed from routing 
tables (i don't use routed/gated)).
To achieve this, I would like "piranha" to be able to manage a third 
interface alias (eth1:1 in my example) for the DMZ.
Is this available already? I'm going to start working on piranha sources... 
Any help would be appreciated!
Thanks,
Pietro Ravasio
