You will need to setup port forwarding to the guest machine.
On the NAT tab in Virtual Network Editor, click Edit -> Port Forwarding. From here you can configure which ports are forwarded from the host machine to the VM.
For example, forwarding host port 8080 to the VM 192.168.83.137:80 should allow you to access the web server on the VM by going to http://127.0.0.1:8080 on the host machine.
