Transport connection failing unable to connect to host machine

I am trying to access my application from two machines… one is my host and other is another laptop connected in the same network…I am able to access the application.
For the ip values in create webrtc transport options i am passing the ipv4 address of my host machine after doing an ipconfig…However the transport is not getting connected for the other machine…but it is fine in the host machine. What should i do?

Can i use tunneling, for example use a port number for webrtc options and then tunnel that port by ngrok…and specify that uri in the ip addresss tring instread of the ipv4 address that i am getting from ipconfig command??
