我想将静态 NAT 应用于 KLRTR 路由器上突出显示的服务器,但问题是接口 s0/0/0 上有帧中继的子接口 (S0/0/0.203)。所以我在 S0/0/0.203 的子接口上应用了 NAT,但是子接口 s0/0/0.203 已经分配了一个 IP(NAT IP 与 KL_ISP 和 KLRTR 之间的 IP 不同),所以它没有像 NAT 翻译一样工作,但发件人没有收到 ping 响应。
在模拟模式模式下,KL_ISP 的数据包失败,不知道为什么即使我在 KL_ISP 上设置了静态路由以进入网络并且其他设备能够 ping。
如果我从 Internet Web 服务器 ping 到其内部本地 IP 上的 DHCP 服务器,则 ping 成功但在外部全局 IP 上 ping 失败。
我将 IP 地址应用于 S0/0/0,然后在其上应用了 NAT,但这也不起作用。
有没有其他方法可以解决这个问题。
谢谢你
