I have a docker bridged network, and two linux containers connected and running.
The two linux machines can ping successfully each other using the network ip respectively 172.19.0.2 and 172.19.0.3
I am using Docker v20.10.17 on Windows, (with WSL2 integration, hopefully this does not matter)
Question
I executed the ipconfig /all, and see no (virtual) adapters on this subnet...
How can I connect my host to this network?
With WSL2 it is kind of crazy what you have to do.
Make sure your WSL2 instance is running.
Windows: start->run - type ncpa.cpl
Pick your WSL vEthernet adapter and your physical ethernet adapter and bridge them.
Note you will lose internet on your windows machine unless you do some other stuff but this should get you to a starting point.

So what I'm trying to do is to use nested VPN connections inside WSL2. The Windows 10 host is logged into one (Cisco AnyConnect, if it makes any difference) VPN, and I'm trying to establish another (openconnect GP protocol) VPN connection inside WSL2, that would get routed through the host OS's established VPN tunnel.
This all works fine with VirtualBox using NAT networking, but I have absolutely no idea how to achieve the same result with WSL2.
Zero experience with Windows networking, so don't really know where to even start (other than Googling, which has been of zero help so far). I have no need for any fancy VLANs or network confs for WSL2 containers. I'm simply using WSL2 to avoid the utter horseshit that is development tools running on Windows.
I've been searching around and found no similar issues have been asked.
My desktop (windows 7) is in LAN, has IP (192.168.3.121).
I installed vmware (windows 7), using NAT connection (172.168.174.128). The guest is able to access internet without problem.
In guest, if I "ping 192.168.3.121", this will be ok.
If I "ping 192.168.3.xxx", will also be ok.
If I "ping 192.168.174.2" (DNS), this will be ok.
If I "ping 192.168.174.1", can't ping.
Note my host Vmnet8's ip is indeed 192.168.174.1. Ping from host also doesn't work.
From host:
"ping 192.168.174.128" (guest IP), does not work
"ping 192.168.174.2", does not work
Both host/guest windows are installed without any other "security/defender/firewall" related softwares.
Anywhere can go wrong?
Thanks.
If you configured your vmware VM to run in a virtualized NAT network, then you will not be able to access/ping your VM from the Host, or anywhere else for that matter, without configuring port forwarding for that virtual NAT network.
If you would like to be able to access your VM from your host you can either:
A) Change the mode of the network adapter for the VM to a bridged adapter. This will make the VM act as if it is just another computer on the same network your Desktop is and will be accessible at an IP such as 192.168.3.122
or
B) Add a Host-Only network adapter to the VM. This second NIC will be connected to a network that has no internet access, but is connected to the host and any other VMs on the same host-only network
Also, check the firewall settings to allow inbound ICMP inside the VM.
You mean that you cannot ping to the VMnet8 interface of your physical PC.
Maybe it is not activated.
It should be activated first by issuing the command at the cmd prompt with the admin's privilege.
C:\Windows\system32>netsh interface set interface name="VMware Network Adapter V
Mnet8" admin=ENABLED
I have seen this issue with two different windows 10 machine & two different version of vmware workstation ( 15 & 16).
One way it works is I start the wireshark & under capture options I select on VMWARE8(default for workstation/need to adjust according to your NAT Interface) & than start ping from My Local Machine to NAT IP of the VM .
It takes time but it works. I do not what triggers this .
My initial thought was it's one of the Windows 10 upgrade but with two different version of windows 10 & this old issue resurfaced.
Navigate to "Control Panel\Network and Internet\Network Connections".
Disable and Enable the VMware Network Adapter VMnet8 and try again.
I was having same problem after the latest release of VirtualBox-6.1.6-137129-Win update. "NAT Network" on any of the guest machine was not working. So i downgraded my virtual box version to 6 and works fine with all my VMs but problem remains in Kali Linux.
NAT Network was successful in giving IP to kali machine but Internet was not working. Problem i found was somehow gateway of kali wasn't set. Then i configured both Gateway and DNS manually and it worked for me.
Make sure that you Uncheck the option "Use this Connection only for resources on this network."
Kali manual configuration for IP, DNS and Gateway
I have an ubuntu VM running in VirtualBox. I am trying to ping it, but cannot. I have the network setting changed from 'NAT' to 'bridged'.
here is the screenshot of the ip address info:
and here is the result of a ping....
i did some google searching, but have not been able to pinpoint the issue yet.... thanks
When you use NAT mode, you will never ping the virtual machine from the host machine because it is the NAT restriction. But when you use the bridged mode, you should be able to ping the virtual machine because it will create a direct path as if both of the machine directly connected. If the ping is fail, perhaps there is some program or application that are blocking the network like a firewall.
I am using a Macbook running 10.6. I am using VMware Fusion to run an Ubuntu Server minimal virtual machine. Ubuntu Server is running your basic LAMP stack.
I do my development in Mac OS. I have VMware share a directory from Mac OS to the Ubuntu Server. Ubuntu Server uses that directory for apache.
I access my server is Mac OS in firefox using the ip address of my virtual machine. This is a pain because I have to find out what the ip address is of my virtual machine each time I boot it up. I could set a static ip address but this causes problems if I move my Macbook from network to network.
Is there any configuration (NAT or Bridged or something) that would let me access my virtual machine from the Mac OS using localhost or something similar?
Thanks
NAT should be OK. Your VM is on a different subnet that way, you can give it the static IP you like, and it won't interfere with the (dynamic) IP on your real network.
What you are looking for is the host-only networking adapter as opposed to the NAT or bridged adapters. This creates a network interface on the virtual machine that only connects the actual host. It is perfectly safe to set an IP address for this interface that does not change, and there will be no tricky NAT getting in the way. It's a little network that only exists for communication between the real host and the virtual host. It's exact purpose is so you can do development like this. I use the same feature on VirtualBox all the time, but VMWare has it as well.
Now, with a host-only adapter you might be worried that your VM now has no access to the Internet. The answer is simple. Just make two adapters. eth0, eth1. Make one of them a bridged or NAT adapter for Internet access. Make the other one the host-only adapter for your development. Most modern Linux distros will automatically route accordingly. I know for a fact that Ubuntu does, because I do it all the time. Again, this is with VirtualBox. Your mileage may vary with VMWare, but I can't imagine it's that different.
I'm using Virtual Box and typing in the computer local address (for instance 192.168.1.100) instead of localhost did the trick.
Maybe I'm misunderstanding your question but why not just add an entry in your hosts file for the virtual machine? That way you can access it with some arbitrarily assigned name (like testmachine) instead of the IP.
This is the first tutorial I found through google: http://decoding.wordpress.com/2009/04/06/how-to-edit-the-hosts-file-in-mac-os-x-leopard/
This would work best if your VM has a static IP, BTW (either no DHCP or configure the DHCP server to give that MAC the same IP every time). That way you don't have to worry about changing the hosts entry every time the DHCP server gives the VM a different IP.
I am running as my Host OS - Win 7 x64 and running an instance of Virtual PC XP. I am running the Cisco ISPec VPN Client on the Guest XP VPC OS and can successfully connect to my company's corporate network.
I cannot run the Cisco IPSec client sw on the Host, because it is 64-bit, Cisco doesn't support 64-bit on its IPSec client products and I don't have alot of choices at the moment in terms of moving to Cisco's SSL VPN client (AnyConnect).
The XP VPC Guest OS is not using the NAT network adapter, but the physical adapter of the machine.
I can ping the Host from the Guest OS and vice versa when Cisco Client is not running on the XP VPC guest OS.
Couple of problems:
When the Cisco client is running and connected the guest OS cannot see the Host any longer.
I would like to be able to access the VPN from the Host when the XP VPC guest is connected to VPN.
For #2, I have tried at least one technique, described: xenomorph.net/use-cisco-vpn-under-vista-x64/
This technique turns on ICS on the Cisco pseudo network adapter.
I could not get this to work. I may have followed the instructions incorrectly, however.
I have also looked at: http://www.pringle.net.nz/blog/PermaLink,guid,12ee0de7-f998-4084-8b06-537b3dbd5d9a.aspx
... which involves using a Loopback adapter and bridging between the host and guest OS. I have not followed this because the instructions are not completely clear.
Lastly, I have seen references on the net regarding a x64 build of OpenVPN, but I am hesitant to go in that direction.
Can anyone steer me in the correct direction regarding what to do?
actually cisco has cisco vpn client for windows 7 64 bit ,you can find it on 4shared.com ,but still cisco does not have client for windows 8
