Why can't I ping the devices in Cisco Devnet lab from my ubuntu running on a VM ? I can access the Devnet CML via https from the VM,I can't ping the IP though,which is weird.I am connected via VPN ofc to the Devnet CML lab.
I can see the routes -CML lab appliance is 10.10.20.161,I can https into it,but can't ping it,Devices inside the lab are also in the same subnet - 10.10.20.175 , .176 etc.., and I can't ping any of those devices.

check if you have any IPtables breaking that connectivity iptables -L

This is what I see,
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
