Prerequisites
 
  
* Download and install VirtualBox
+
openwrt-x86-generic-combined-ext4.img.gz
* Download and install the Virtualbox Guest Additions (needed for USB connectivity among others)* Download the openwrt-x86-64-combined-squashfs.img image, from snapshots/targets/x86/64/(On Linux, downlaod the openwrt-x86-64-combined-ext4.img image)
+
gunzip openwrt-x86-generic-combined-ext4.img.gz
* Open a terminal and go in the folder where you have downloaded the file (sorry, the tool has only a command line interface)
 
* Convert it to native VB format by writing this in command line (the same for Windows, Mac and Linux. Sadly this tool does not have graphical user interface):

:!: It's recommended to place the disk image in a permanent place before linking it with VB. If you move it afterwards, VB will not find it anymore and will complain about this issue on next start (or when you try to start the VM). It will offer a guided procedure to link the disk image again, so don't worry.

VM setup
 
  
This part of the configuration will deal with setting up networking manually.

Untuk bridged adapter di adapter 3, kita bisa melakukan
The configuration you will set up by following this tutorial is:
 
 
 
* eth0 of the VM on mng (management) interface, fixed address 192.168.56.2, set in Virtualbox as Host-only Adapter on adapter vboxnet0. This interface will be always available to the host even if host or VM are disconnected from any network.
 
* eth1 of the VM on wan interface, dynamic address, set in Virtualbox as NAT. This interface will be used to access the Internet through whatever setup the host also uses.
 
* (optional) eth2 of the VM on lan interface, configured depending on your local network, set in Virtualbox as Bridged Adapter. This interface allows other devices (host included) to connect to the VM as if it was a physical device in the local network. Will only work if there is already a local network of some kind.
 
* For a setup with 2 bridged physical network cards WAN/LAN Setup see troubleshooting. The rest of this guide applies to a setup with 2 physical cards as well.
 
 
 
Virtualbox settings
 
Host-only network adapter
 
 
 
we first need to make sure there is a Host-only network adapter and that it has the right settings
 
 
 
* click on File → Preferences → Network
 
On macOS, this setting may be found through File > Host Network Manager…
 
* click on Host-only Networks tab and then if you don't see a vboxnet0 entry click on the + icon on the right of the window to add a new one.
 
Now select the vboxnet0 entry, and click on the screwdriver icon on the right to open its settings.
 
* IPv4 Address should be 192.168.56.1, IPv4 Network Mask should be 255.255.255.0, IPv6 Address should be empty and IPv6 Network Mask should be 0
 
 
 
(optional) you can also set the DHCP server as shown in the screenshot if you want to have dynamic addresses to the VM, but for this tutorial it is not required as we set a static address in the VM itself
 
 
 
press OK to save and close until you are back to Virtualbox Manager interface again.
 
Network Settings
 
 
 
Open the VM's settings
 
 
 
Go in the Network tab
 
 
 
configure Adapter 1:
 
 
 
    with Host-only Adapter
 
    select vboxnet0 as (adapter) Name
 
    click on Advanced and in Adapter Type select Intel PRO/1000 MT Desktop
 
    Promiscuous mode should be set to Deny unless you have good reasons to enable it.
 
 
 
    Configure Adapter 2
 
        with NAT
 
    (optional) Configure Adapter 3
 
        with Bridged Adapter
 
        in the Name field select the name of the network card (ethernet or wifi) of your PC that connected to a local network. On Windows it has a full device name, on Linux it will have codenames like eth0, eth1 for ethernet or wlp2s0 for wifi.
 
        Click on Advanced and do the same you did for Adapter 1's advanced options
 
 
 
VM Settings
 
 
 
:!: due to limitations, the keyboard in the VM's terminal screen is set as US, so some (or most) of your keys will not print the right symbols.
 
Also, due to the fact that what you see there is a bare machine terminal and not a smart thing like a ssh program (Putty/Kitty/whatever) or a terminal emulator program, you cannot copy-paste text into it.
 
Don't worry, most of the setup will be done after you are connected with SSH (remote terminal) that does not have any of these issues.
 
Look at this US keyboard layout to find what button you need to press on your keyboard to generate the right symbol.
 
 
 
    Boot into your VM
 
    Wait 4 seconds for GRUB to boot automatically
 
    Press Enter to activate the console when the boot messages have finished to scroll by. It may take two or three minutes for “entropy” to be generated (random: crng init done with OpenWrt 17.01.4). Until there is sufficient entropy, ssh and other cryptographic functions may fail.
 
    let's see the current network configuration
 
 
 
    root@openwrt:~# uci show network
 
    network.loopback=interface
 
    network.loopback.ifname='lo'
 
    network.loopback.proto='static'
 
    network.loopback.ipaddr='127.0.0.1'
 
    network.loopback.netmask='255.0.0.0'
 
    network.globals=globals
 
    network.globals.ula_prefix='fd1b:e541:8f1a::/48'
 
    network.lan=interface
 
    network.lan.type='bridge'
 
    network.lan.ifname='eth0'
 
    network.lan.proto='static'
 
    network.lan.netmask='255.255.255.0'
 
    network.lan.ip6assign='60'
 
    network.lan.ipaddr='192.168.1.1'
 
    network.wan=interface
 
    network.wan.ifname='eth1'
 
    network.wan.proto='dhcp'
 
    network.wan6=interface
 
    network.wan6.ifname='eth1'
 
    network.wan6.proto='dhcpv6'
 
 
 
Note that the default LAN address of 192.168.1.1 is present on first boot.
 
 
 
    edit the network configuration to allow SSH access by writing these commands and pressing enter:
 
        uci set network.lan.ipaddr='192.168.56.2'
 
        uci commit
 
        reboot
 
    now your VM should be accessible from SSH, user root (no password) address 192.168.56.2
 
    after you have logged in successfully, we can actually do the true configuration, please copy-paste the following block of code and press enter:
 
 
 
    uci batch <<EOF
 
    set network.mng=interface
 
    set network.mng.type='bridge'
 
    set network.mng.proto='static'
 
    set network.mng.netmask='255.255.255.0'
 
    set network.mng.ifname='eth0'
 
    set network.mng.ipaddr='192.168.56.2'
 
    delete network.lan
 
    delete network.wan6
 
    set network.wan=interface
 
    set network.wan.ifname='eth1'
 
    set network.wan.proto='dhcp'
 
    EOF
 
 
 
    now write uci changes to check if the setting configuration was loaded correctly. If you see the following (the network.mng entries MUST be the same as the ones shown here, the network.wan might be slightly different), everything went well
 
 
 
    root@openwrt:~# uci changes
 
    network.mng='interface'
 
    network.mng.type='bridge'
 
    network.mng.proto='static'
 
    network.mng.netmask='255.255.255.0'
 
    network.mng.ifname='eth0'
 
    network.mng.ipaddr='192.168.56.2'
 
    -network.lan
 
    -network.wan6
 
    network.wan='interface'
 
 
 
    if all is well, save config with uci commit && reboot, if all is NOT well, write reboot to erase the temporary changes and find a way to set the above configuration manually.
 
    close and open again the SSH terminal when the VM has restarted, with same connection parameters (user root and 192.168.56.2)
 
    now you should have both internet access (try a opkg update) AND a management interface with a static address you can connect your SSH client program to even if your PC is disconnected from a local network.
 
    the optional Bridged Adapter on Adapter 3 isn't crucial for basic functionality and is also specific for your own local network parameters. In my own network (and in most home networks) it will work fine if you write
 
 
 
    uci batch <<EOF
 
    set network.lan=interface
 
    set network.lan.ifname='eth2'
 
    set network.lan.proto='dhcp'
 
    EOF
 
    uci commit
 
 
 
 
 
    If you have more complex requirements you will have to set that up on your own by reading the documentation, or through luci.
 
    you can now install packages to this images as normal, you will probably want to install luci, write opkg update && opkg install luci, then you can connect to the VM's luci by typing 192.168.56.2 in your browser address bar or click on this link to get there.
 
 
 
Troubleshooting
 
 
 
    If you rebuild the disk image, and VirtualBox complains about invalid UUIDs for the disk
 
        You need to remove the disk from both the VM and also from the Virtual Media Manager
 
        Then add the disk image to the VM again
 
 
 
    If you want to use a bridged VPN on your device to bridge it to your local network you need to set the
 
        Promiscuous Mode of the corresponding Bridged Network Adapter to “Allow All” or else your local network won't be bridged properly to your vpn bridged network
 
 
 
    You can also have 2 physical network interfaces on your main operating system that is hosting the virtual machine. In this case
 
        Use one Network Adapter as WAN and in VirtualBox you select Bridged Adapter with Promiscuous Mode to Deny
 
        Use the other Network Adapter as LAN and in VirtualBox you select Bridged Adapter with Promiscuous Mode to
 
            Deny if you don't want to expose bridged virtual networks to your physical network
 
            Allow All if you want to connect your bridged virtual network to your physical network
 
 
 
Run with Virtual Box automatically on Start of Windows OS
 
 
 
    Ordered List ItemImport the following entry to your registry or add it manually:
 
        [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
 
        “VB-MYDEVICE”=“\”C:\\Program Files\\Oracle\\VirtualBox\\VBoxManage.exe\“ startvm \”NAMEOFVBINSTANCE\“ –type headless”
 
 
 
    Alternative create 2 shortcuts and use the Windows Task sheduler
 
        “C:\Program Files\Oracle\VirtualBox\VBoxManage.exe” startvm MYDEVICE –type headless
 
            Create a task in the Scheduler triggered by logon of any user as action the shortcut
 
        “C:\Program Files\Oracle\VirtualBox\VBoxManage.exe” controlvm MYDEVICE acpipowerbutton
