kvm KVM VM's on Ubuntu Server

[Milen]

I have Ubuntu Server 18.04 LTS with some Samba shares, Nextcloud and other services but i want to create a VM with KVM which I can access it outside LAN.

I have basic KVM knowledge and at the moment I only can create VM and connect via SSH tunneling and this is the problem because I need to connect outside the LAN. I read a few things in Google that I need to create bridge to connect to VM's outside the LAN. I created bridge then I installed Lubuntu and from the VM I have access to the internet also I checked DHCP list from my router and I can see the VM name and the IP but I can't connect with VNC to the VM without SSH tunneling.

Can someone help me to figure out what I am doing wrong?

I can give you whatever logs you want to fix the problem.

Thanks in advance.

Just to clarify: does the VM have an IP-address similar to the host it's running on? Ie. they are both on the same network?

Yes the server on which is hosted Lubuntu VM is in the same network as the pc from which i am trying to connect to the VM.

 

The output from "ip addr" command:

Lubuntu installation is fresh and i didn't install anything.

Is there a way to access the VM with the ip of the VM from WAN only with any VNC client ?

[Windows7ge]

What IP does the Lubuntu VM have? I don't see it mentioned above.

My Ubuntu server is 192.168.1.29, my Lubuntu VM is 192.168.1.7 and my laptop from which im trying to connect to VM is 192.168.1.241.
