Can't ping guest from LAN

Hi

I use WX 15.5 Pro on a Windows 10 64 bit PC 16GB RAM

The routing function is enabled on the PC and the firewall was disabled during my tests

When I create a VM with a NAT network interface I can't ping the guest VM from the PC's LAN

The PC running VMWARE can ping the guest VM

The guest VM can ping ressources situated on the PC's LAN

Surely I must have omitted a step when setting up my VM ?

regards
