Let Host use Guest internet connection - virtualbox

Host: Linux Mint 21. Guest: Win10
I have to use a vpn client (zywall) that is only available on Windows.
I don't even know if it's possible, but I would like to use the Guest connection (connected via zywall) by the Host machine, almost as a second network interface.

How to create bridged connections in Virtualbox (Windows 10)

I am trying to create a Linux virtual machine hosted in Windows 10 that has a unique IP address from the host. I understand that a bridged connection is required for this but can not find simple instructions for how to accomplish this.
When I change the network settings in Virtualbox to 'Bridged Adapter' and set the Promiscuous mode to 'allow all' the virtual machine cannot connect to the internet. I assume there is something in the Windows host that needs to be done but can not find what that is.

Unable to connect Ubuntu 16.04 Server in VirtualBox (host Windows 10) to internet via bridged wireless adapter

Strange, on work I can normally connect to internet with my Ubuntu 16.04 Server via briged wireless adapter, but at home I can't (when "A start job is running" sequence is over and after I log in to server there is no internet connection). I also tried to connect at friend's place but also result is negative.
Bridging with Lan adapter works perfectly, but I would rather use Wi-fi bridged adapter if I can. NAT or Host-only are not an option. Is it possible that router that my ISP gave me is problem? Any thoughts?
Change the adaptor to wireless, present below Bridged Adapter. And try.

How do I block a loopback connection to some port on Windows?

Adding an inbound Windows Firewall rule (via COM from C++) for local port 80 and addresses ANY, 127.0.0.1 or 0.0.0.0 does not block a local browser from accessing a local web server running on port 80. For debugging/testing purposes, I need to simulate loss of network connectivity between two programs running on the same computer. Is there a way to do this programmatically, on the command line, or with a tool?
In this question, they say allegedly there is no way to do this in the Windows Firewall:
How do I block localhost connections with the Windows 7/2008R2 firewall?
Is there a way, other than Windows Firewall, just to simulate loss of network connectivity between programs running on the same computer?
There is WIPFW -- a Windows port of FreeBSD's IPFW. However, I failed to get it to block localhost connections. Maybe you'll have more luck.
Alternatively, you can try a hack. If your programs establish a connection using the localhost host name instead of directly by the 127.0.0.1 IP address, you may change your hosts file to point the localhost name to some non-existing or otherwise unreachable address.

virtualbox bridged interface won't connect to internet

I'm trying to connect an ubuntu 12.04 to my local network + internet, i would like it to be directly reachable from the local network, NAT interface don't do it so i tried setting up a bridge (in the virtualbox GUI). But then i can access any other host on the LAN from the guest, but i can't access internet, the DHCP seems to work fine since my guest OS gets an IP in the correct range and with the correct mask. However i can't even ping the router which connect me to the internet (the same machine as the DHCP server).
here's my configuration:
host machine: linux mint debian edition X86-64
guests: win7 64 and ubuntu server 12.04 x86-64 (both have the same issue)
router-gateway-dhcp: livebox from orange ISP
host network interface: wifi usb dongle with chipset RTL8191SU (which works fine for my host)
I know the bridged mode isn't supported by all wireless adapter, but isn't it weird that i can access local network but not the internet?
maybe the problem comes from the gateway itself?
any advice would be very appreciated
In general, there is no problem in using VirtualBox in bridged mode on a laptop. I use it very often and on different platforms, yet it can be related to your network adapter.
Can you try to debug your network by using tcpdump (if familiar) or wireshark? I once had the problem that the mac address got rejected by the router. Can you check if the router is permissive for unauthorized mac addresses or anything alike?

How to connect from a VMware guest machine to the server installed on a Windows 7 host machine?

How to connect from a VMware guest (virtual) machine to the server installed on the host (physical) machine? Things like typing "localhost" in the address bar of a browser in a guest machine don't work. My host machine's OS is Windows 7 64 bit with WMware Workstation installed on it, if it matters.
EDIT: The Bridged network connection in combination with referring to 192.168.0.10* from the guest machine did work (replace * with a digit starting from 0 until it works).
If you use "Bridged" Network Connection (see Virtual Machine Settings: Network Adapter), your VM will be given an IP address on the same LAN as your host machine. At that point, you can just HTTP to your host's IP address, eg. http://192.168.0.100
You can also do that with the other options, but with NAT and Host-only (if I recall correctly) your host machine will appear to your guest machine to have a different IP address than its real LAN address. So Bridged is the easiest and is likely your best bet, unless you have some specific needs.
First thing to do: Check that you have the network up and running. Try to ping the host system or any web site from the console of the guest OS, let's say ping www.google.com.
If you received any answers then please try writing the IP number of the host machine in the addressbar of the browser on the guest machine (NOT localhost :P). You should be able to see any web service running (Tip: Open the console of your windows 7 and type ipconfig, then find the ethernet adapter corresponding to VMWare and you'll find the IP number of your host system).
If you didn't received any answer at all when you did ping then check the network configuration of VMWare to use Bridged Connection --at least that's how it works for me.
Good luck!
In a guest machine, localhost refers to the virtual machine itself. Refer to the host just as you would from any other machine: by its IP address.
Note that it may be using a second "virtual" network adapter to communicate with the guest. Check the VMware to find out, and to find the second IP address.
Just use the same IP sub net for your VMware machine, if your windows system has ip address class C 192.168.0.10 So assign 192.168.0.120 IP to your Vmware machine and make sure that Firewall allow the traffic in vmware and also add the listener port manually in vm machine. go to system - administration- firwal-add port 1521.
Thanks
