FreeBSD 2 網卡

我們有帶有 2 個帶有FreeBSD的網卡的伺服器。一張用於網際網路的卡（工作正常），另一張用於本地網路連接（到192.168.227.0/24網路）。當我嘗試使用 ip 192.168.227.1 ping 本地網路的網關時，我收到消息**“ping：發送到：主機已關閉。”** 網關正常且線上 - 所有其他伺服器（使用 Ubuntu）都可以輕鬆連接到該網路。所以也許我的配置文件中有一些錯誤。

如果配置：

igb0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
       options=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,              TSO4>

ping -c5 192.168.227.24 可以 - 100%。

還有網路10.6.200.0我需要通過192.168.227.1路由此伺服器，但主要目標是從網關獲取 PING。

您需要使用以下設置打開 ip forwarding/etc/rc.conf
