Virtualbox:從訪客到主機的連接埠轉送不起作用

Virtualbox:從訪客到主機的連接埠轉送不起作用

在下面視訊盒我有一個基於 ubuntu 的虛擬機網路位址轉換

我習慣像下面這樣在 vbox 上進行連接埠轉送配置

Name     Protocol  IP host  Port host  IP Guest  Port Guest
myrule   TCP                3000                 3000

但是當在連接埠 3000 上執行我的網路應用程式時;我無法在主機的瀏覽器中打開它。 (並且它在我的來賓虛擬機中表現不佳)

ifconfig在我的來賓虛擬機器中顯示以下內容:

ifconfig
enp0s8: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.0.3.15  netmask 255.255.255.0  broadcast 10.0.3.255
        inet6 fe80::b612:8769:ba28:6e2e  prefixlen 64  scopeid 0x20<link>
        ether 08:00:27:42:89:7b  txqueuelen 1000  (Ethernet)

        TX packets 2669  bytes 373394 (373.3 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Boucle locale)
        RX packets 229607  bytes 231076789 (231.0 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 229607  bytes 231076789 (231.0 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

和我的/etc/網路/接口文件看起來像這樣:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

建議?
