Do you have the Linux VM configured with NAT or Bridged networking?

NAT networking does not expose your virtual machine to other systems on the network that the Host can reach. Try using Bridged networking instead. 

(or else you'll have to get familiar with configuring port forwarding for the NAT networking and how to use it - but I'm not 100% sure if that can be done from Workstation Player, though - you might need Professional).
