Routing issue

I have a 2K12 hyperV machine with 2 NIcs (192..1.11 & 192..112)

I recently downloaded an appliance that creates a private switch with a network id 192.168.56.1, and the VM has 192.168.56.101. From IE or Chrome on the win 2012 box, when I typehttp://192.168.56.101 I reach the machine (web site inside it) but I can not do it from another machine (laptop or desktop they are on the same network as the hyper-V 192.168.1...) using IE or chrome. pinging the ip from the hyperv machine responds but not from others. I checked the route print and have this on the hyper-V

192.168.56.0    255.255.255.0         On-link      192.168.56.1    261
 192.168.56.1  255.255.255.255         On-link      192.168.56.1    261

the question is why I can connect from the machine itself but not others? What is needed to be added in the routing table on the other machines in order to be able to join this appliance from another machine

Thanks in advance
