Accessing ubuntu virtual machine host from windows browser

I have a virtualbox ubuntu machine running a hellow world flask app.

I tried having the app display on 127.0.0.1:5000 and 0.0.0.0:5000

But both when I try to load up on my windows browser don't resolve.

When I run ifconfig in ubuntu virtual machine I get this:

ifconfig -a
eth0      Link encap:Ethernet  HWaddr 08:00:27:6f:2c:93  
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe6f:2c93/64 Scope:Link

          TX packets:559 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:61322 (61.3 KB)  TX bytes:73104 (73.1 KB)

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

And when on my windows machine I run ip config I get this:

ipconfig

But for some reason when I go to 192.168.56.1 in my windows browswer it loads a white page. If I go to 192.168.56.1:5000 it says it can not connect.

In my virtual box I have it "attached to: NAT" and port forwarding rules show

ssh TCP 127.0.0.1 host port 2222 guest ip is empty and guest port is 22

My flask app shows

 * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
 * Restarting with stat

Also tried with

 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat

answer to your question you can find in VirtualBox documentation: https://www.virtualbox.org/manual/ch06.html 6.3.1. Configuring port forwarding with NAT

You can just forward port 5000 from guest OS (Ubuntu) to host one. On the host side you can use the same port number (if it's not occupied by someone else, sure)
