Accessing a webserver running on guest on host

[defiant]

Hello all,
I am using mac osx as a host for my lubuntu installation guest system.
I am using docker to run a webserver and trying to access the webpage from the host system.

The issue is I am able to get to the webpage if tried from the guest os, but not the host.

My current set up has a host only adapter and a nat network, both with static ips from same range.

Docker IP: 172.17.0.3
Guest OS IPs:
192.168.56.5
192.168.56.100

Now when I tried setting the webdomain to 192.168.56.5 or 172.17.0.3 using /etc/hosts I was able to access the web page.
So can anyone please help me figure out a way to fix this issue?
Thanks in advance.

Docker is a program that relies on VirtualBox but modifies its configuration files in unknown ways to us. It is not supported on these VirtualBox user forums, they have their own support channels. If you are having this problem with a standalone version of VirtualBox, then we can continue this discussion.
