Allow VMs attached to internal switch on hyper-V win2k19 access Internet

Hi, I have 4 VMs attached to an internal switch with IPs 10.10.0.*, assigned 10.10.0.1 to the switch.

One of the NICs on the host has the 192.168.1.70 which I shared its connection with the internal switch but I am not able to browse internet from the VMs.

What can be missing? Thanks
