Hi so i am trying to setup a little LAN in virtualbox, i have zeroshell running as the router and a windows 10 VM. I have configured my first ethernet adaptor for zeroshell to use a bridged adaptor, then giving it a dynamic ip address, to my understanding it should be the same ip address to my host machine(I did it at tafe and it was working fine) but m router seems to be giving it its own ip address, i have also setup a second ethernet adaptor to be an internal networl adaptor with a static IP of 192.168.10.1, So i can ping my router from my windows 10 vm and i can ping the bridged ethernet adaptor but i cant ping my host machine or get access the internet can soemone please help?

Bridge network did not get an IP address.
Using shared network address 192.168.205.2
I'm developing a simple web application with springboot in Windows 8.
When I deploy jar file into docker in Ubuntu and run the container, I can see it works on address 10.0.2.15:8082 which is a local IP address, correctly.
What I want is to connect this IP address in my Windows 8 then I will use postman to post some JSON variables etc. But I can't connect 10.0.2.15:8082 from Windows 8.
My VirtualBox adapter attached to NAT and also some rules are given:
I also tried to change host and guest rules otherwise, but didnt work either.
When I run the application in Windows 8 and check it with 192.168.56.1:8082, it gives success and also I can see the same result in Ubuntu with the same address. but can't get it to work otherwise.
I expect to connect ubuntu's localhost in my Windows 8.
I have found the answer;
After shutting down vm, i added second adapter as Host-only Adapter. After starting virtual machine, in terminal by entering "ifconfig" command you can see ip4 address for host-only adapter (in Windows it is Ethernet adapter Virtualbox Host-Only Network). When you try to enter that address in windows and ubuntu, it shows the result.
Also that 192.168.56.1 address is Windows Virtualbox Host-Only Network IPv4 address in my PC.
I believe NAT adapters do not allow direct connection between host and guest, you will need a second Host-only Adapter for that purpose.
See this link for a nice explanation.
A network bridge transparently relays traffic between multiple network interfaces. And it is protocol independent, working at network layer 2.
However, it is common to assign an ip address to a network bridge. Docker network bridge has an ip address and it cannot work properly any more after deleting the ip address. What's more, kvm and xen also use a bridge to control network, they often take over the network from host network interface(such as eth0) and work with an ip address assigned.
I think it is strange to use an ip address when talking about a network layer 2 appliance. What happend when assigning an ip address to a network bridge? How a bridge works with an ip address?
I have an Ubuntu VM (with a Varnish Cache) running in VirtualBox on my local computer. When I'm at home the ip address of my computer is 192.168.178.34. I use the network bridge to connect the VM with my computer. The ip of the VM is then 192.168.178.38. That allows me to reach the cache-server e.g. like that: http://192.168.178.38:6081/index.html
The problem is, i want that this URI is static. My goal is to share the vm with somebody and make a documentation about how to use the cache-server. Therefore it would be great if the ip adress would be always the same, even if the vm will be started in a VirtualBox on a different computer.
Is there a way to set a fixed ip address for the vm, regardless of the host computer?
Thanks a lot!

You can set up a host-only network adapter, which uses the subnet 192.168.56.0/24 by default. Inside the VM, you can set a static IP address.
I'm running VirtualBox on a ubuntu (host), the VM i'm using is fedora (guest). VirtualBox is setup to use the NAT network adapter, and I'm able to get to the internet.
i use Port Forwarding to access ssh and the rails web server
port Forwarding Rules
<NAT>
<DNS pass-domain="true" use-proxy="false" use-host-resolver="false"/>
<Alias logging="false" proxy-only="false" use-same-ports="false"/>
<Forwarding name="Rule 1" proto="1" hostport="5679" guestport="22"/>
<Forwarding name="Rule 2" proto="1" hostport="3080" guestport="3000"/>
</NAT>
now i can access internet on guest machine , and i can logging through ssh
but i cannot access the Rails web server on port 3080
i tried :
localhost:3080
10.0.2.15:3080 #the guest IP
what i can do all i need is SSH and internet connection and open the web site i host on gust machine by Browser in host machine
thanks
Just a stab in the dark here but this might be your issue...
When you provision a new Linux Virtual Machine in VirtualBox, the Network settings for that VM are set to 'NAT'. This results in your new VM being assigned a 10.x.x.x address.
Change this setting to Bridged mode, which will assign your VM an address within the same subnet as your host (most likely 192.168.x.x).
Try to connect to the site running on your host.
If you're still not able to access the site running on localhost, confirm the app isn't blocking connections from your new VM. Add a rule in to your access list (possible iptables) permitting tcp port 80 traffic from your VM's address (found using ifconfig).
Happy hunting!
In your VB you have to set network only with host. It is in preferences->network.
Then you can access your virtual machine via 192.168.56.101 from ubuntu. Port forwarding set on this network card. List it with ifconfig. I recommend to use iptables for port redirects.
