Vyatta 目标 NAT 不工作

在超过我们的第一个 VRRP 组中的 IP 限制后，我们遇到了向 vyatta 设备添加新 IP 的问题。工作中列出的所有 IPvrrp-group 1都很好，但我添加的任何IPvrrp-group 2都没有。

我们可以看到流量进入，但我们想要工作的流量 (443) 永远不会到达 NAT。但是，ping 流量进来并返回（这应该不起作用）。NAT 位于防火墙之前，但我们已经检查过它以确保我们没有遗漏任何东西并且它有 0 次命中。任何想法将不胜感激。

流量从端口 443 进入但不退出

防火墙命中的 NAT 表中没有任何内容

set zone-policy zone outside interface 'bond1'
set zone-policy zone outside interface 'bond1v1'
set zone-policy zone outside interface 'bond1v2'
