Dear Users
Since a few weeks i have a problem with connecting to and from my VM's. First i thought has to do with my Windows 11 migration. but now i'm back on windows 10 but the problem still exists. First what is my Configuration:
I try to give as much as possible information so:

Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
So I can not connect to host, but i can connect to the gateway.
If i use Host only network:

This workout well too.
And now the most strange part... If i let Nmap do a ping scan i get the following result(s):
Starting Nmap 7.93 ( https://nmap.org ) at 2022-12-13 10:35 W. Europe Standard Time
Nmap scan report for domain-on.vm.com (192.168.122.130)
Host is up (0.00s latency).

Nmap scan report for 192.168.122.1
Host is up.
Nmap done: 256 IP addresses (3 hosts up) scanned in 37.87 seconds
So all Nmap detects all the (expected) IP-addresses. I'm unable to ping the same addresses and i'm unable to go to the VM's domain.
Basically i don't have any clue anymore where to find a solution.
After weeks using Bridged mode instead of NAT mode. The problem disappeared equally fast as it appears. No clue what is changed but it works again
Small update:
Currently i use the VM in Bridged mode. For a big part of the work i need to do with the VM it work out well. But that doesn't mean i don't have any issues...
A few issues i noticed so far while using bridged mode:
- Last time i wrote:

This workout well too.
Today i noticed that when I'm in bridged mode the host only connection don't work.
- Also i had issue that i was unable to ping while Nmap was able to ping the VM

Now i have basically the reversed issue.
I can't ping from VM to host but Nmap is able to ping:

So basically still no clue what and why i have these issues... Every tip or idea is welcome
Why does your gateway show as blank? Is your adapter set for static or DHCP?
