因此，我有一台 Ubuntu 机器，其接口 eth1 上有多个 VLAN，每个 VLAN 都有相同的 IP 地址 (172.16.0.2)。我需要能够同时远程登录到机架上的设备，这些设备的 IP 地址也相同 (172.16.0.1)。我能想到的唯一方法是通过 IPtables 将流量转发到特定接口的特定目标端口。
例如我希望能够运行“telnet 172.16.0.1 12001”并将这个出站接口 eth1.101 定向到 172.16.0.1:23 或运行“telnet 172.16.0.1 12002”并将这个出站接口 eth1.102 定向到 172.16.0.1:23。
我尝试了好几次 iptables 设置，但都没有成功。有没有 iptables 专家可以帮我设置？
