I create a VM in win7 host. The net mode is NAT, and IP of VMware Virtual Ethernet is 192.168.169.1. The VM (its OS is debian) can connect the host by eth0. Win7 can connect VM, too.
Than I create docker in VM. The net mode is bridge, and IP of bridge Ethernet (docker0) is 172.17.0.1. the ip of eth0 in docker is 172.17.0.2. And VM can ping to docker. docker can ping to VM, too.
But win7 host can not ping to docker. How can I connect docker in host?

My host machine is a Windows 10 OS.
My Virtual Box guest machine is a Ubuntu OS.
I launch a server and a gateway in my virtual machine in the following addresses:
https://127.0.0.1:8089/
https://127.0.0.1:18443/
I dont have any problem to access them from the guest machine. However, I would like to have access to those addresses from my windows host. How can I get it?
In order to access services hosted on your virtual machine from your host you need to configure your virtualbox network settings for that machine to bridged network, which will allow it to have an IP inside your LAN. You can find more information on virtualbox network types here.
Another option would be port forwarding with a NAT network configuration, where your host port would be a port over 1024 and the guest port would be your virtual machine ports (8089 and 18443).
I have built two VM, and both use the same network configuration which are NAT for the first network adapter, and Host only Ethernet Adapter for the second adapter.
This is my network configuration for both VM :
First VM
eth0 : dhcp
eth1 : 10.0.0.10 255.255.255.0
Second VM
eth0 : dhcp
eth1 : 10.0.0.20 255.255.255.0
How to solve the problem? should i do or reconfigure something?
In VMWare, Host-Only mean VM's can ONLY network with the host, not other vm's. but in Parallel Desktop and VirtualBox it work.
So in a simple way, if you want to block the network between Second VM and Internet, you could choose NAT and set some firewall with iptable on host.
In VMWare website, you should route between Two Host-Only Networks like this link.
There is more information about Host Only Network.
I have the following setup: A virtual machine, started with qemu is running on an ubuntu laptop. I also have a raspberry pi 4 booted from a sd card connected over ethernet with the laptop. My goal is to establish a network connection between the VM and the Raspberry. So far i worked with a tap (tap0) and a bridge (br0) to connect the VM with my network adapter (eth0).
I was expecting that The VM and the raspberry should now be able to ping each other but i can only do the following:
Ping from VM to bridge
Ping from Raspberry to bridge
Ping from bridge to Raspberry or VM
Where could the problem be?
I found the problem. It was the firewall! Make sure to enable ip forwarding here.
sudo iptables -P FORWARD ACCEPT
if you are in a closed network as in my case this shouldn't be a problem.
[Edit - Solved ]
Problem Unable to ping between host and VM guest
Settings
Guest OS : Ubuntu
Host OS: Windows10
Firewall settings are disabled on windows 10
Type of network adapter on Virtual Box is bridged
IP config
Windows:
IPv4 Address. . . . . . . . . . . : 192.168.0.110
Ubuntu:
inet addr:192.168.0.110 Bcast:192.168.0.255 Mask:255.255.255.0
Troubleshooting
Tried pining the gateway but no hope
Tried changing the IP of the Ubuntu guest (since both host and guest having the same IP) but still no hope
Changed my network (connected to a mobile hotspot) and it Worked!
Conclusion:
I was connected to a WLAN repeater, may be this was the issue but I have no idea how that could be related!
this might help others, but i had a host machine with multiple physical eth ports on my linux box. i had a virtualbox loaded with windows with a bridged network adapter to eth2. but only eth1 on the host machine had a physical network cable plugged in, eth2 did not. in order to use a bridged adapter, you need a cable plugged in.
ethtool eth2
look for linked detected: no
Seems something wrong with your network settings. How windows and guest have same IP address(192.168.0.110).
Which network type you are using
NAT or Bridged or Host only
For virtual networking refer:

I am running Boot2Docker in Virtual Box on Windows, using VB bridged networking. The IP address of my PC (192.168.2.2) and of the VM (192.168.2.30) is determined by the DHCP server.
I have configured the docker bridge as follows:
File /var/lib/boot2docker/profile:
EXTRA_ARGS='--bip=192.168.2.192/25 --fixed-cidr=192.168.2.224/27'
From my Windows PC I can successfully ping the folloing IP addresses:
192.168.2.30 (ip address of eth1 in the Docker Host)
192.168.2.192 (ip address of docker0)
However I cannot ping any container that I start. E.g. for container IP 192.168.2.226,
I get a reply from 192.168.2.2 (my PC address) that the Desitination Host is unreachable.
How can I get this to work?
I figured it out in the meantime:
On Windows 7, from an elevated cmd shell do:
route add 192.168.2.224/27 192.168.2.30
This way the IP packets find their way to the containers!
