may be problem on NAT?

[Alejandro Feijoo]

 I want to create a cluster using piranha but i only have 2 servers, one for
    LVS router, one for LVS backup and both for Real Servers.
    The conf is the follow:

    ProliantA:
    public ip: 193.144.34.XXX
    private ip 10.1.1.1
    virtual public ip: 193.144.34.ZZZ
    virtual private ip: 10.1.1.3
    ProliantB:
    public ip: 193.144.34.YYY
    private ip 10.1.1.2


    I run piranha and make the following config:
    serial_no = 143
    primary = 193.144.34.XXX


    primary_private = 10.1.1.1
    service = lvs
    backup_active = 1
    backup = 193.144.34.YYY
    backup_private = 10.1.1.2
    heartbeat = 1
    heartbeat_port = 539
    keepalive = 6
    deadtime = 18
    network = nat
    nat_router = 10.1.1.3 eth1:1
    nat_nmask = 255.255.255.240
    debug_level = NONE
    monitor_links = 1
    virtual WEB {
         active = 1
         address = 193.144.34.ZZZ eth0:1
         vip_nmask = 255.255.255.0
         port = 80
         send = "GET / HTTP/1.0\r\n\r\n"
         expect = "HTTP"
         use_regex = 0
         load_monitor = ruptime
         scheduler = rr
         protocol = tcp
         timeout = 6
         reentry = 15
         quiesce_server = 0
         server proliantA {
             address = 10.1.1.1
             active = 1
             weight = 2000
         }
         server proliantB {
             address = 10.1.1.2
             active = 1
             weight = 1000
         }
    }


    But the result is, nat not work... because when i active pulse on both
    servers eth0:1 not start propietly and... if any petition to
    193.144.34.ZZZ    may pass to other server this service not work


    any can help me?
