关于CentOS配置错误的Dante 1.4.1

Question

我正在尝试在具有大量虚拟NIC的CentOS版本6.7（最终）计算机上配置Dante v1.4.1。我希望外旋同样相同。 我试过这个配置：

internal: ip1 port = 1
internal: ip2 port = 1
.
.
.
external: ip1
external: ip2
.
.
.
external.rotation: same-same
method: none
user.privileged: <user>
user.unprivileged: <user>
client pass {
        from: <external_ip> port <port-range> to: 0.0.0.0/0
}
pass {
        from: <external_ip> <port-range> to: 0.0.0.0/0
         protocol: tcp udp
}

但我一直收到此错误消息：

warning: getoutaddr(): using external.rotation = same-same, local address <external_ip> was selected for forwarding from our local client <external_ip> to target ip, but that local address is not set on our external interface(s).  Configuration error in /etc/sockd.conf?

如果我不使用external.rotation: same-same一切正常，但我想让所有进入vNIC的传入流量退出同一个vNIC。

有什么想法吗？
