ubuntu virtualbox nat network not working

(Consult our guide to forwarding ports on routers here.

Your router is forwarding ports correctly – this is only necessary if you want to access the virtual machine from the Internet.

(This only applies to NAT mode with port forwarding – the host computer’s firewall doesn’t interfere in bridged networking mode.) Alternatively, you can configure Bridged Networking to enable external hosts to directly access. NAT is performed on traffic through the host interface to the outside network. The default virtual network configuration is known as Usermode Networking.

The firewall software on your host computer isn’t blocking the connections. There are a few different ways to allow a virtual machine access to the external network.(You may need to allow the server program in the guest operating system’s firewall.) The firewall software running inside your virtual machine isn’t blocking the connections.Remember that this is only part of the process of making the server software inside a virtual machine reachable. If you’re using VMware Player, you can still use bridged networking mode to make your server accessible. There are methods for installing it yourself by extracting the vmnetcfg.exe file from the VMware Player installer, but I couldn’t locate the vmnetcfg.exe utility in the latest version of VMware Player, VMware Player 5.0 – it may no longer be included in the installer.

Unfortunately, this utility is not included with VMware Player.
