可以在主机和客户机之间 ping 通，但无法使用 Virtualbox 访问 Web 服务器

为什么我可以使用 VirtualBox 在主机和客户机之间来回 ping，但我无法从主机访问安装在客户机上的 Web 服务器。我使用的是仅主机网络。

Host Ubuntu 10.10 
vboxnet0 - 192.168.56.1
ping to self, works
ping to guest, works
access to web server in guest, FAILS

Guest Fedora 13
eth1 - 192.168.56.101
ping to self, works
ping to host, works
access to web server in host, works

答案1

检查防火墙设置以及客户机上的 httpd 配置中可能的访问限制。

答案2

您是否偶然在浏览器中配置了网络代理？

我也想尝试一下 - 虚拟服务器可以自行访问本地 Web 服务器吗？是否有 Linux 防火墙阻止非本地主机访问端口 80？

答案3

我发现解决这个问题的方法是确保 Windows VirtualHost-Only 适配器设置为 ip 范围的 .1 地址，因此我的虚拟盒主机适配器是 192.168.58.20，但 Windows 适配器的 ip 是 192.168.58.1

答案4

我检查了客户机上的防火墙守护程序，发现它正在运行，于是我停止了它，现在我可以访问主机上已安装的 EBS (Oracle Enterprise Business Suite)。见下文：
