Networking :: How To Do NAT In VirtualBox
May 10, 2011
I'm using VirtualBox 4 on OpenSuse 11.3.
I've 6 vm with different OS.
My company uses a net in 10.x.x.x. But I can't use IP of that range (only one for the host). I use IP for my vm in the range 192.168.x.x.
I need my vm to communicate each other, to the host and outside. From outside (10.x.x.x), don't need to access 192.x.x.x.
How do I have to configure Virtualbox?
- Tried with host-only. VM can see each other, but not the outside.
- Tried with NAT. Then VM can't see each other.
- Tried with bridge. Then can't see outside.

Virtualbox, is great, except that I have no wireless networking or USB support. Problem one, is USB support. As far as I know there is a personal free use version of Virtualbox that includes USB support, however I can't find this copy to download it. Any ideas where I can find it? Second problem, I have an integrated wireless networking card in my laptop, that Ubuntu recognizes with no problems, but Virtualbox can't even "see" the device. I found a tutorial that addresses this know issues with wireless and Virtualbox, but I don't understand the instructions

Quote:
Wireless Networking Setting up a normal bridged network generally doesn't work if you're bridging from a wireless card to VirtualBox. A simple script that utilises the parprouted tool will allow your VM full access to the wireless network. You will require parprouted to do this: sudo apt-get install parproutedNext, using your favorite text editor, create and edit the script, for example:
sudo nano /etc/network/if-up.d/vbox_networkThen, enter the script (replacing $USER with your username (or whoever you intend to run virtualbox as)). Replace wlan0 with the name of your wireless interface. Use an available IP address on your network for tap0 (I have used 192.168.1.100 in this case):
sysctl net.ipv4.ip_forward=1
VBoxTunctl -b -u $USER
ip link set tap0 up
ip addr add 192.168.1.100/24 dev tap0
parprouted wlan0 tap0Finally, make sure the new file is executable by root: sudo chmod 700 /etc/network/if-up.d/vbox_networkNow your networking script is installed, the virtual interface tap0 will be available on boot for VirtualBox. Rather than reboot, let's just run the script now:
sudo /etc/network/if-up.d/vbox_networkThe final thing to do is tell VirtualBox to use the new virtual device tap0. Open VirtualBox, highlight a VM and click settings. Now choose the network option and select Host Interface on the 'attached to' drop down menu.
In the Interface Name text box, enter: tap0 Click ok and start your VM. The VM should now behave as though it was another physical machine on your network!! For more information on the process up to this point, please visit Bridged Networking with VirtualBox on Linux Hosts Using DHCP in the Guest VM It was possible to get DHCP to work on the guest virtual machine. Instructions were taken from here. Because parprouted does not relay multicast, we need to use an additional helper daemon to manage this. I tried dhcp-helper and bcrelay, and had the most success with bcrelay.
Use it as follows:
sudo apt-get install bcrelay
sudo bcrelay -i tap0 -o wlan0At this point, my /etc/network/if-up.d/vbox_network is as follows:
#!/bin/sh
sysctl net.ipv4.ip_forward=1
[code]....
bcrelay -i tap0 -o wlan0 &It seems that I have to start the script by hand after boot. Other than that, host networking now seems to work fine (this issue should be solved by adding the "#!/bin/sh" line just at the beginning of the script.

I can connect to the Internet using the Windows Drivers for my USB iBurst pppoe modem running in a VirtualBox VM running Windows XP on my Ubuntu 10.10 host. I haven't been able to get this working under Linux.
Is there any way I can connect to this from the Linux host.

Observed on two host systems both with openSUSE 11.3 32 bit using ext4: When a big files, in this case a 1.2 GB and a 1.7 GB is copied from DVD, usb harddrive or shared folder into a Windows 7 32 bit guest system, the copied file is corrupted. The md5sum has changed and until the guest system has been rebooted successive md5sum tests on the same file comes up with various results... After a reboot md5sum tests show consistent results, but a sum different from the original file.

I've got a problem with getting my VPN connection from my virtual machine working (a XP64 running in VirtualBox). I really need to get it working so that I can nuke my windows partition, and because I would like run linux programs while using my XP VPN connection (as I need to run some XP programs at school). I've found this manual on how to do it on Ubuntu, but I am doubt about how to translate it to Fedora (and I really prefer Fedora). [URL]

I've installed fedora 15 on virtualbox as my guest OS.I've configured bridged networking and I've set my router to assign an IP to it.when it boots up,I have 2 devices shown via "ifconfig" which is "lo" and "p2p1" and none has the ip assigned to it.I'm unable to access the Internet. How can I configure it to do so?I've tried following this tutorial: [URL] but the file "ifcfg-ethX" doesn't exist...it only has ifcfg-lo..... I've installed fedora 15 spin edition which doesn't have a GUI for me to edit network settings...

I recently purchased a block of 5 IPs from Comcast. I have a computer running Arch Linux connected to the Comcast gateway they gave me. On my connected computer I have 2 Windows XP virtual machines running. Now I was wondering how can I make each of those virtual machines have a different public IP, because currently the only thing I can get working is have the computer and both virtual machines sharing the same public IP.

VirtualBox-3.2.8 (the non-free version) seems to be able to tell my wlan0 connection to 'split' into 2 IP addresses: one for the OS inside VirtualBox and one for the host. My router runs Tomato and I can see both real and virtual machines with different IP addresses in the device list (I can also visit httpd running on my host machine from inside the virtual machine). Is it possible to replicate this outside of VirtualBox?
In my case, I would like to be able to 'split' wlan0 into 2 with one IP address for normal network use and the other 'assigned' to eth0. eth0 is "shared to other computers" from NetworkManager and is currently connected to a Belkin router. My goal is to have this Belkin router assigned an address that all machines in my Tomato network can access (I have an OpenBSD 4.7 home server connected to the Belkin).
Whilst VirtualBox was running I tried to see if bridge-utils was being used:
Code:
[root@1 ~]# brctl show
bridge namebridge idSTP enabledinterfaces
...but it appears as though it isn't.

I've installed Debian inside Virtualbox on Mac OS 10.5.
I want to set up networking so I can (a) reach the outside internet from inside Debian (Virtualbox), and (b) reach the virtual Debian from my Mac. (I don't need to be able to reach the virtual Debian from anywhere but the Mac.)
I can't seem to figure it out. If I set the Virtualbox networking to "NAT", I can reach the outside world from Debian, but I can't reach Debian from Mac OS. If I set the Virtualbox to "Host Link Adapter", I can reach Debian from Mac OS, but I can't reach the internet from Debian.
I'm sure I've set up the way I want before, and I don't remember doing anything special for that, so I must be missing something simple today.

run a Hamachi client in a Windows virtualbox and be able to set it up (using network bridging, maybe?) like Hamachi was running in the host itself.
I'm most definitely not a networking expert, but I thought it would be worth a try to see if anyone had any ideas. Hamachi for linux is outdated and unstable.
Also, if this isn't possible and anyone has another cross-platform zero-config VPN solution as stable as Hamachi

As of yesterday I have this perculiar problem. When I try to ssh into my account I have on a linux server where I keep some of my files (I'm using Cisco VPN) ssh claims it can't find the address.It's worked fine before, and if I connect using putty in Virtualbox on the same machine it works.The problem applies both to command line ssh and NetBeans (which uses a java client).I've tried setting SSH not to resolve DNS in the config file but it doesn't help.

So I'm wanting to learn a bit more about networking (ok, ALOT more), and I was thinking of trying to setup a virtual network via Virtualbox on my desktop, and as seperated from the internet as humanly possible (preferably no connection whatsoever).
Ignoring a few of the obvious problems (like my little dual core potentially running half a dozen VMs on 2G RAM), I am wanting some guidance as to what programs I would need or some documentation on setting things up.
I have no real clue where I would want to start with this, but I want it as a testbed for future toying with, to learn from, and just generally as something for me to hack at to see what does what, how, and why.

I am trying to learn about networking and am looking to set up a mini network between three bare bones Centos machines in Virtualbox. I set up the machines with a static IP. In the Virtualbox I am using NAT and have the IPs as follows
Centos-1
IP: 10.0.2.15
Gateway: 10.0.2.2
DNS: 10.0.2.3
Centos-2
IP: 10.0.2.16
Gateway: 10.0.2.2
DNS: 10.0.2.3
Centos-3
IP: 10.0.2.17
Gateway: 10.0.2.2
DNS: 10.0.2.3
On all machines i can ping google.com, and yum updates, but I can not ping any other machine. It says they are unreachable. NOt really sure what to do. Any help would be much appreciated.

I am trying to config linux box as router.
I have CentOS 5.5 client and host in VBox. I can't connect them (I am using bridge adapter mode) as I don't have router in between.
I just created DHCPD on host, and followed
[URL]
But that don't seem to work also. Host is 192.168.1.10 and client is 192.168.1.100 but when I ping host from client, it says Destination host unreachable.

Second issue: I have a modem which is no discovered by the win XP.

My USB-modem and my freerunner phone is no longer recognized by fedora. Last time this happened I just reinstalld Fedora because I had no id�a what caused the problem. But now I recognized that virtualbox was the last package I installed before the problem occured.
I tried to uninstall virutalbox but the problem remained. Is there a way to reset all the network settings without reinstalling fedora?

Trying to set up a VPN connection from with Virtual Windows XP (virtualbox) and the network shows verifying user name and password but then times out and give me a message that it could not connect to the serve.
Since I could connect from a Windows system at another location, I assume there is something in Ubuntu that is preventing the connection so I tried to set up a VPN connection in Ubuntu.
I installed "network-manager-pptp" and "pptp-linux" as mentioned in the documentation but when I try to create a VPN connection using [main menu]>[System]>[Preferences]>[network connections] the VPN tab has a padlock on it. I set up the VPN but did not put a DOMAIN name on it because the server does not have a DOMAIN and it did not appear to be necessary on the dedicated Windows machine.
In spite of configuring the VPN connection, I cannot find the connection anywhere so I can see the server at the other end.
When I try to use [main menu]>[places]>[Connect to Server] using [windows share] and enter the IP number of the server, I get the message "Cannot display location smb:// {server IP address}"
And if anyone knows why the Virtual windows cannot connect.

How can I give my VirtualBox OSE a static IP address. My virtualbox is running Windows Xp 32-bit, and I am wanting to give it a static IP Address.
For example, my ubuntu pc has the ip address, 192.168.2.101 I want my VirtualBox to have the ip address, 192.168.2.201
I also want my Virtualbox to have port 95 open.

Our company uses a customized vpnc (based on and almost the same as vpnc 0.5.3). I first tested it on a Windows host under Virtualbox everything works straight away. But when I want to use it on a Linux host directly it always ends in "No response from target". I have tested this on Fedora 12 and the latest Ubuntu.
I thought of firewall settings but iptables -L on Ubuntu returns an empty list even.

I am having trouble for routing port 80 from a Billion adsl modem to a guest server in VirtualBox. There are quite few different changes from my last setup so I kind of confuse which one is wrong.
I used to use have the setup belowusing modem Linksys WAG354G use static ip 192.168.1.100 for my machine use static ip 192.168.1.102 for my guest VirtualBox server guest OS is serving http listening on port 80 i use bridge from my host OS for VirtualBox set my modem to direct all traffic on port 80 to 192.168.1.102 host OS was Fedora 11
now I useusing modem Billion 7404VNPX use same static address and configuration host OS is Fedora 13
main issue is I cannot reach the guest OS if I navigate to my modem ip address. (e.g. http://192.168.1.1) if I change the modem to direct all traffic to my host OS ip address (192.168.1.100) it works nicely.
I have tried to disable and enable the firewall without any luck.

I created a F14 x86_64 guest OS in VirtualBox4 (hosted by F14 x86_64) and configured it to get its IP from my router but it won't do so on boot. The other guest OS's (Fedora 14 i386, 2x Oracle EL5) are able to get their IPs on boot.
I checked the setting in the network manager and they show that the interface is to be activated on boot but it doesn't. When I log in and run ifup eth0 as root it works.

I currently have VirtualBox installed on my Ubuntu 9.10 Desktop. I have windows xp as a guest os and it has network shares on it. My question is, is there a way for another computer to access those network drives on the guest os in virtualbox? I don't want to search for hours on end on google, a simple no would be fine - however if it is possible let me know because when I am in windows on another computer that has windows as a host os it sees it in the windows network folder but it says "....network location not found" or something similar but it still shows a pc picture of the virtual os of the virtual box program running in ubuntu.
