Does your workstation have two active network interfaces?
Some modern Linux distributions install with a hypervisor that runs the 
Linux OS as a guest to that hypervisor.  The hypervisor has a management 
network interface and the linux OS has a separate one.  Each are on the 
same physical network connection.
