Not able to access a Tomcat container using Docker toolbox on windows

Hi, I followed part 1 tutorial given by Johnny Tu on thiw website, when I issue the command
Docker run -d -P tomcat:7
I get a new container spinned but not able to access the web page at http://docker-machine IP:port/
I do ping http://docker-machine IP; it works fine, I telnet the ip with the specified port it seems listening but when I fire a browser I get page or site nor reachable.
The IP for the docker-machine is as the virtualbox network adapter IP is and DHCP starts at
So what can be the problem
Thanks in advance

Just discovered that the problem was with Microsoft Edge. I fired Google Chrome and the tomcat server page opened like a charm
