lvs-tun 节点未连接

我正在使用隧道设置 LVS 集群。目标是拥有两个导向器服务器（在不同的数据中心）和一个真实服务器（目前，稍后将在负载平衡中添加更多）。通过端口 80、443 和 8080 访问真实服务器

我已经成功配置了我的主控制器，它工作得很好，所有端口都打开了，数据流动良好

但是，备份导向器只能连接到端口 443 上的真实服务器。这是我在 /var/log/messages 中得到的输出：

（忽略缺少的端口 80 线，我当时禁用它进行测试）

似乎 nanny 进程只能连接到端口 443 上的真实服务器。然而，使用 netcat 或 curl，我在其他 2 个端口上得到了正确的响应。

这是我的 lvs.cf（作为单个服务器）：

serial_no = 36
primary = 103.13.yyy.yyy
service = lvs
backup = 0.0.0.0
heartbeat = 1
heartbeat_port = 539
keepalive = 6
deadtime = 18
network = tunnel
debug_level = NONE
virtual http {
    active = 1
    address = 103.13.xxx.xxx eth0:1
    vip_nmask = 255.255.255.255
    port = 80
    send = "GET / HTTP/1.0\r\n\r\n"
    expect = "HTTP"
    use_regex = 0
    load_monitor = none
    scheduler = rr
    protocol = tcp
    timeout = 6
    reentry = 15
    quiesce_server = 0
    #Define nodes
    server node1 {
        address = 103.29.zzz.zzz
        active = 1
        port = 80
        weight = 1
    }
}
virtual https {
    active = 1
    address = 103.13.xxx.xxx eth0:1
    vip_nmask = 255.255.255.255
    port = 443
    send = "GET / HTTP/1.0\r\n\r\n"
    expect = "HTTP"
    use_regex = 0
    load_monitor = none
    scheduler = rr
    protocol = tcp
    timeout = 6
    reentry = 15
    quiesce_server = 0
    #Define nodes
    server node1 {
        address = 103.29.zzz.zzz
        active = 1
        port = 443
        weight = 1
    }
}
virtual http_8080 {
    active = 1
    address = 103.13.xxx.xxx eth0:1
    vip_nmask = 255.255.255.255
    port = 8080
    send = "GET / HTTP/1.0\r\n\r\n"
    expect = "HTTP"
    use_regex = 1
    protocol = tcp
    #Define nodes
    server node1 {
        address = 103.29.zzz.zzz
        active = 1
        port = 8080
        weight = 1
    }
}

真实服务器上的隧道已经设置正确（毕竟443端口是工作的）

所以我被难住了......有没有办法强制节点处于活动状态，即使nanny没有找到它？
