![FreeBSD 2 网卡](https://linux22.com/image/608372/FreeBSD%202%20%E7%BD%91%E5%8D%A1.png)
我们的服务器有 2 张网卡,FreeBSD一张卡用于互联网(工作正常),另一张用于本地网络连接(192.168.227.0/24net)。当我尝试使用 ip ping 本地网络的网关时192.168.227.1我收到消息“ping:发送至:主机已关闭。”网关正常且在线 - 所有其他服务器(安装有 Ubuntu)都可以轻松连接到该网络。所以也许我的配置文件中存在一些错误。

ping -c5 192.168.227.24 正常 - 100%。
还有网络10.6.200.0我需要通过哪里路由这个服务器192.168.227.1,但主要目标是从网关获取 PING。
答案1
您需要使用以下设置打开 IP 转发/etc/rc.conf
gateway_enable="YES"
